K-shell x-ray-production cross sections in 6C, 8O, 9F, 11Na, 12Mg, and 13Al, by 0.75- to 4.5-MeV protons

Creator: Yu, Y. C.; McNeir, M. R.; Weathers, Duncan L.; Duggan, Jerome L.; McDaniel, Floyd Del. (Floyd Delbert), 1942- & Lapicki, Gregory
Description: This article discusses K-shell x-ray-production cross sections. Abstract: K-shell x-ray-production cross sections are reported for elements with K-shell x-ray energies between 277 eV (C) and 1487 eV (Al). The x-ray measurements were made with a windowless Si(Li) detector that was calibrated for efficiency by comparing bremsstrahlung spectra from electron bombardment of thin foils of aluminum, silver, and gold with theoretically determined bremsstrahlung spectral distributions. The x-ray-production cross-section measurements are compared to first-order Born and perturbed-stationary-state with energy-loss, Coulomb deflection, and relativistic corrections (ECPSSR) ionization theories using single-hole fluorescence yields. The ECPSSR and first-order Born theoretical predictions are, in general, in close agreement with each other and both generally fit the data quite well.

Principal Resonance Contributors to High-Valent, Transition-Metal Alkylidene Complexes

Principal Resonance Contributors to High-Valent, Transition-Metal Alkylidene Complexes

Date: July 1991
Creator: Cundari, Thomas R., 1964- & Gordon, Mark S.
Description: This article discusses principal resonance contributors to high-valent, transition-metal alkylidene complexes. Stationary points on each potential energy surface are characterized and compared to experimental information where available; as long as a suitably flexible valence basis set is used, good agreement between theoretically calculated and experimentally determined geometries is obtained.

Toxicological Case Study of Dallas' Central Wastewater Treatment Plant Effluent and Ambient Trinity River Samples: 1989, 1990, 1991

Toxicological Case Study of Dallas' Central Wastewater Treatment Plant Effluent and Ambient Trinity River Samples: 1989, 1990, 1991

Date: [1991]
Creator: University of North Texas. Institute of Applied Sciences.
Description: "This study was implemented voluntarily by personnel at Dallas Water Utilities in response to concerns that the Dallas Central Wastewater Treatment Plant was adversely affecting downstream water quality." The treatment plant was studied to determine whether it was "discharging toxic materials in toxic amounts to the Trinity River" (p. 1).
