Tables of Electron Radial Functions and Tangents of Phase Shifts for Light Nuclei (Z=1 through 10)

Description: From Introduction: "This Monograph, supplemented by ORNL-3207 [9], should eliminate completely the need for use of approximate formulas (e.g. those of Kotani and Ross [10]). The formulation of the problem has been summarized in sec. II. This is followed in sec. III by a discussion of the methods used in numerical calculations. Sec. IV contains a detailed explanation to facilitate the use of present tables."

Trajectory-Wise Analysis of Immobilized Plasma Including Electrons. Machine Calculations

Description: Abstract: "The trajectory analysis of an immobilized plasma has been generalized to include the presence of electrons having a far similar radius of gyration and, therefore, fitting readily into the broader scale structure established by the ions. This problem has been adapted to machine calculations and the results for various strengths plasmas have been calculated."

Corrosion Characteristics of Uranium : An Electron Diffraction Study

Description: Abstract: "The initial product formed on relatively oxide-free uranium has been shown by electron diffraction to be the alpha or low temperature form of uranium hydride. Such as oxide-free surface has been prepared by polishing the metal within the electron diffraction unit while maintaining a vacuum of 10^-7 mm Hg. Uranium dioxide lines appear later and grow in intensity. Electron diffraction studies are reported on vacuum annealed metal."

Anisotropy of conduction electrons in n-InSb and extrinsic and intrinsic properties of HgCdTe

Description: The anistropy of the orbital and spin properties of conduction electrons in InSb has been measured simultaneously using a cyclotron-resonance type experiment. This represents the first time that the anistropy of effective mass in InSb has been directly measured using an optical method.

Hydromagnetic Instabilities Caused by Runaway Electrons

Description: "The possibility of the excitation of hydromagnetic instabilities caused by a beam of runaway electronics is investigated. It is found that if the wave length and frequency of the wave are such that the Doppler shift of the frequency due to the runaways' motion causes the electrons to see their cyclotron frequency, and if the electric field rotates in the same direction as the electrons do about the confining magnetic field, then an instability occurs."

Photofragment Coincidence Imaging of Small I- (H2O)n Clusters Excited to the Charge-transfer-to-solvent State

Description: The photodissociation dynamics of small I{sup -}(H{sub 2}O){sub n} (n = 2-5) clusters excited to their charge-transfer-to-solvent (CTTS) states have been studied using photofragment coincidence imaging. Upon excitation to the CTTS state, two photodissociation channels were observed. The major channel ({approx}90%) is a 2-body process forming neutral I + (H{sub 2}O){sub n} photofragments, and the minor channel is a 3-body process forming I + (H{sub 2}O){sub n-1} + H{sub 2}O fragments. Both process display translational energy (P(E{sub T})) distributions peaking at E{sub T} = 0 with little available energy partitioned into translation. Clusters excited to the detachment continuum rather than to the CTTS state display the same two channels with similar P(E{sub T}) distributions. The observation of similar P(E{sub T}) distributions from the two sets of experiments suggests that in the CTTS experiments, I atom loss occurs after autodetachment of the excited (I(H{sub 2}O){sub n}{sup -})* cluster, or, less probably, that the presence of the excess electron has little effect on the departing I atom.

Photon and electron data for use in accelerator applications

Description: In accelerator applications we need photon and electron data, as well as computer codes that utilize this data, in order to predict results inexpensively and safely. In this paper I will first cover the current status of available photon and electron data, with emphasize on the improved detailed that has only recently been added to our data bases. Next I will cover the availability of this data and computer codes that use it.

Electron-Population Analysis and the Dipole Moment of the LiH ¹Σ⁺ Excited State / A.M. Karo

Description: Abstract: "Detailed consideration is given to some properties of the first excited electronic state. Following the analysis proposed bv Mulliken, SCF LCAO-MO coefficients are used to obtain qualitative information about the electron distributions. Comparison is made with earlier work with respect to the description of the excited-state dipole moment, the effective electric moment between the ground and excited states is also calculated. From this, the oscillator strength for the first allowed transition is computed as a function of the internuclear distance."

On Point Designs for High Gain Fast Ignition

Description: Fast ignition research has reached the stage where point designs are becoming crucial to the identification of key issues and the development of projects to demonstrate high gain fast ignition. The status of point designs for cone coupled electron fast ignition and some of the issues they highlight are discussed.

Description: This memo discusses the analysis of the high-energy x-ray distribution from a laser-induced plasma to determine the superthermal electron distribution. The methods of deconvolution outlined in I are similar to formulae derived in the literature not including and including effects due to electron stopping. In II the methods are applied to an x-ray spectrum from an Au disc irradiated by ARGUS.
