Electron Detachment In Low-Energy Collisions Of H- And D- With He, S. K. Lam, John B. Delos, L. Champion, L. D. Doverspike May 1974

Electron Detachment In Low-Energy Collisions Of H- And D- With He, S. K. Lam, John B. Delos, L. Champion, L. D. Doverspike

Arts & Sciences Articles

Measurements and calculations have been made of elastic scattering and electron detachment in collisions of H− and D− with He at energies of 5-120 eV. The measurements show no other inelastic processes occurring in this energy range. The mechanism responsible for electron detachment is assumed to be the crossing of the H− bound state with the continuum of free states; the bound state is then assigned a complex energy. The measured elastic scattering differential cross section shows no structure except at Eθ∼200 eV deg, where there is a region of downward curvature in the graph of logσ vs θ. This …


Studies Of The Potential Curve Crossing Problem. Iii. Collisional Spectroscopy Of Close Crossings, John B. Delos Apr 1974

Studies Of The Potential Curve Crossing Problem. Iii. Collisional Spectroscopy Of Close Crossings, John B. Delos

Arts & Sciences Articles

Using a previously developed semiclassical theory of electronic excitations, the cross sections that result from potential-curve crossings are calculated for a model system. The phenomena appearing in the differential cross sections are displayed and discussed.
