- Spin-Flip Probability in the Inelastic Scattering of 7.48-MeV Neutrons from the 4.43-MeV State of 12C
- This article discusses spin-flip probability in the inelastic scattering of 7.48-MeV neutrons from the 4.43-MeV state of 12C. An (n, n'y) coincidence method was used to determine the neutron spin-flip probability in inelastic scattering. The experimental method consists of neutron time-of-flight and neutron-y coincidence technique with the deexcitation y ray detected perpendicular to the neutron scattering plane. The angular distribution of the spin-flip probability for the first Jπ =2+ excitation in carbon has been determined at an energy of 7.48 MeV. The neutron spin-flip results were found to be similar to the proton spin-flip results in this energy region. The experimental results were compared to the predictions of an antisymmetrized distorted-wave calculation which did not provide good fits to the spin-flip data. The spin-flip predictions were sensitive to the optical-model parameters and were dominated by spin-orbit distortion in the elastic channels. The mechanism of core polarization dominated the inelastic amplitudes, masking the effects of the effective interaction on the extracore nucleons. digital.library.unt.edu/ark:/67531/metadc139478/

- Elastic and inelastic scattering of 1.5-MeV neutrons by the even-A isotopes of zirconium and molybdenum
- This article discusses elastic and inelastic scattering of 1.5-MeV neutrons by the even-A isotopes of zirconium and molybdenum. Abstract: Differential elastic and inelastic cross sections were measured for 1.5-MeV neutrons scattered by the even-A isotopes of zirconium and molybdenum. The scattering samples were enriched isotopes of ⁹⁰Zr, ⁹²Zr, ⁹⁴Zr, ⁹²Mo, ⁹⁴Mo, ⁹⁶Mo, and ¹⁰⁰Mo. The cross sections were measured using a dynamically biased neutron time-of-flight spectrometer. The differential cross sections have root-mean-square relative and normalization uncertainties of 2 to 3.5% and 7 to 7.5%, respectively, for elastic scattering, and 6 to 13% and 9 to 15%, respectively, for inelastic scattering. Isotopes with similar level structures have almost identical elastic angular distributions. The entire set of data was theoretically fitted using the optical-statistical model with resonance-width-fluctuation corrections. The calculated elastic differential cross section was assumed to be an incoherent sum of shape-elastic and compound-elastic scattering. At the minima in the angular distributions the cross sections were dominated by compound-elastic scattering. digital.library.unt.edu/ark:/67531/metadc146595/
- Nuclear lifetime of states in ⁹⁴Tc and ⁹⁶Tc via the pulsed-beam, direct-timing technique
- This article discusses nuclear lifetime of states in ⁹⁴TC and ⁹⁶TC via the pulsed-beam, direct-timing technique. The mean lifetimes of the 333 keV level in ⁹⁴TC and the 119 and 315 keV levels in ⁹⁶TC were measured by the pulsed-beam, direct-timing technique. The values obtained for the mean lifetimes are: τ(333 keV)=2.2(-0.3)(+0.5) nsec, τ(119 keV)=37.0(-0.3)(+0.6) nsec, and τ(315 keV)=2.9(-0.2)(+0.5) nsec. The transition strengths are in agreement with those for other transitions in this mass region. digital.library.unt.edu/ark:/67531/metadc146597/

The experimental values are compared to the nonrelativistic plane-wave Born approximation (PWBA), the binary-encounter approximation, and the PWBA with binding energy and Coulomb deflection corrections.

- L-shell x-ray production cross sections for light ions on Sm, Yb, and Pb
- This article discusses L-shell x-ray production cross sections for light ions on Sm, Yb, and Pb. L-shell x-ray production cross sections for the Ll, Lα₁,₂, Ly₁, and Ly₂,₃₍₆₎ have been measured for ¹H, ⁴He, and ⁷Li on Yb and Pb and for ⁴He and ⁷Li on Sm. The energy ranges for the incident-ion species were 0.3 to 2.4 MeV/amu for ¹H, 0.15 to 4.4 MeV/amu for ⁴He, and 0.9 to 3.0 MeV/amu for ⁷Li. Comparisons of the Lα₁,₂, Ly₁, and Ly₂,₃₍₆₎ x-ray production cross-section data have been made to the predictions of the plane-wave Born approximation (PWBA) and the PWBA with corrections for Coulomb deflection and/or binding-energy effects. The comparisons show that for the individual x-ray production cross sections, there are problems associated with the binding-energy correction calculations for the Ly₁ and Ly₂,₃ x-ray data. Furthermore, measurements of the ration of Lα₁,₂ to Ly₂,₃ x-ray intensities do not support the use of an increased effective binding energy in the PWBA formulation. digital.library.unt.edu/ark:/67531/metadc139486/

- K-shell ionization of elements Ca to Zn for 0.5 to 2.5-MeV/amu 14N-ion bombardment
- This article discusses K-shell ionization elements Ca to Zn for 0.5 to 2.5-MeV/amu 14N-ion bombardment. Abstract: Target K-shell x-ray production cross sections, x-ray energy shifts, and Kβ/Kα ratios have been measured for 7-35-MeV 14N ions on thin solid films of Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn. Comparisons of the data were made with theoretical predictions obtained from the binary-encounter approximation and the planewave born approximation (PWBA). These theories were found to overpredict the experimental data by a factor of 10 at the lower energies. However, at the lower energies, the PWBA, with modifications for increased target electron binding, Coulomb deflection, target electron polarization, and relativistic effects produced results in good agreement with the experimental data was found which increases as the ratio of Z1/Z2 becomes larger. Corrections to the fluorescence yields attributable to multiple ionization processes and the addition of electron capture contributions to the previously indicated direct ionization theories produced results in excellent agreement with the experimental data with the exception of those for the light elements at the highest energies. digital.library.unt.edu/ark:/67531/metadc146601/
- Thermochemical Investigations of Nearly Ideal Binary Solvents. 3. Solubility in Systems of Nonspecific Interactions
- This article discusses thermochemical investigations of nearly ideal binary solvents. Abstract: The simple model which has previously led to successful predictive equations for the partial molar excess enthalpy of a solute in nearly ideal binary solvents has been slightly modified for application to the partial molar excess Gibbs free energy (excess chemical potential) of the solute in these systems. Three predictive equations are derived and tested for their ability to predict solubility in mixed solvents from measurements in the pure solvents. The most successful equation involves volumetrically weighted interaction parameters for the excess Gibbs free energy relative to the Flory-Huggins entropy of mixing, and predicts solubility in 22 systems containing naphthalene, iodine, and stannic iodide as solutes with an average deviation of 1.5% and a maximum deviation of 4%, using no adjustable parameters. digital.library.unt.edu/ark:/67531/metadc152443/
- K-shell x rays of selected elements from Nb through Gd for incident protons and alpha particles from 0.6 to 2.4 MeV
- This article discusses K-shell x-rays of selected elements from Nb through Gd for incident protons and alpha particles from 0.6 to 2.4 MeV. Abstract: K-shell x-ray production cross sections and Kβ/Kα ratios are presented for 0.6- to 2.4-MeV protons and alpha particles incident on thin targets of selected elements from Nb to Gd. The Kβ/Kα ratios are compared to the theoretical predictions of Scofield and agree within 10%. The experimental cross sections are compared to the theoretical predictions of the plane-wave Born approximation (PWBA) and the PWBA modified to include binding energy, Coulomb deflection, and relativistic effects. It is seen that the PWBA modified for binding energy and Coulomb deflection effects agrees with the experimental data for Nb to within uncertainties, but its predictions are lower than the data by larger amounts as the target Z increases. Inclusion of an ad hoc semiclassical relativistic correction to the theoretical cross section, as suggested by Hansen, improves the agreement with the data, but overestimates the data for the highest-Z elements. digital.library.unt.edu/ark:/67531/metadc146602/
- Projectile charge-state dependence of K-shell ionization by silicon ions: A comparison of Coulomb ionization theories for direct ionization and electron capture with x-ray production data
- This article discusses projectile charge-state dependence of K-shell ionization by silicon ions. X-ray production cross sections measured in K-shell ionization of ₂₁Sc, ₂₂Ti, ₂₉Cu, and ₃₂Ge by 52-MeV ₁₄²⁸Si(+q) projectiles with q=7 to 14 are reported, which demonstrate, through their charge-state dependence, the validity of a recently developed electron-capture theory with a reduced binding effect. Furthermore, the data provide evidence for the applicability of the perturbed stationary-state theory of direct ionization for values of 0.44 ≤ Z₁/Z₂ ≤ 0.67. digital.library.unt.edu/ark:/67531/metadc139480/

- K-shell ionization of elements ₁₅P to ₂₈Ni for 0.4 to 3.8 MeV/amu ₅¹⁰B-ion bombardment
- This article discusses K-shell ionization of elements ₁₅P to ₂₈Ni for 0.4 to 3.8 MeV/amu ₅¹⁰B-ion bombardment. Abstract: K-shell x-ray production cross sections, Kβ/Kα x-ray intensity ratios and Kα and Kβ x-ray energy shifts have been determined for thin solid targets of ₁₅P, ₁₉K, ₂₀Ca, ₂₁Sc, ₂₂Ti, ₂₃V, ₂₅Mn, ₂₆Fe, ₂₇Co, and ₂₈Ni for 4-38-MeV ₅¹⁰B ion bombardment. Comparisons of the cross sections were made to direct Coulomb ionization and electron-capture theories by means of fluorescence yields corrected for multiple-ionization effects. The dominant contribution to K-vacancy production for these projectile-target combinations is believed to be direct ionization. Electron capture is expected to be important only for the lighter target elements and then primarily at the higher velocities. The direct-ionization theories employed were the binary-encounter approximation and the plane-wave Born approximation (PWBA) both of which overestimated the experimental data especially at the lower incident ion velocities. The PWBA was modified for increased target-electron binding, Coulomb deflection of the incident ion, polarization of the target-electron wave functions due to the passage of the incident ion, and relativistic target-electron velocities. The experimental data were found to agree quite well with the sum of the theoretical predictions of the modified PWBA and electron capture. digital.library.unt.edu/ark:/67531/metadc146599/

- Projectile-charge-state dependence of target L-shell ionization by 1.86-MeV/amu fluorine and silicon ions and 1.8-MeV/amu chlorine ions
- This article discusses projectile-charge-state dependence of target L-shell ionization by 1.86-MeV/amu and silicon ions and 1.8-MeV/amu chlorine ions. Lα x-ray-production cross sections have been measured for solid targets of ₆₀Nd, ₆₇Ho, and ₇₉Au for 1.86-MeV/amu ₉¹⁹F and ₁₄²⁸Si, and 1.8-MeV/amu ₁₇³⁵Cl ions as a function of the incident charge state. From the projectile-charge-state dependence of the cross sections, both direct-ionization and electron-capture contributions were extracted for a comparison to Coulomb ionization theories. The data provide supporting evidence for the theory of electron capture with a reduced binding effect. With standard fluorescence and Coster-Kronig yields uncorrected for multiple-ionization effects, the direct ionization theories did not simultaneously reproduce the projectile-Z₁ and target-Z₂ dependences of the data. digital.library.unt.edu/ark:/67531/metadc139481/
