Cross Sections for Electron Scattering from Cadmium: Theory and Experiment

Abstract

Results from the application of optical potential, relativistic optical potential, relativistic convergent close-coupling, and binary encounter Bethe models to electron scattering from gas-phase cadmium are presented. In particular, integral cross sections for elastic scattering, summed discrete electronic-state excitation, and ionization scattering processes are reported over an extended incident electron-energy range. Total cross sections are constructed by taking their sum. Measurements are presented for elastic scattering and for excitation to the 51P1 state. The theoretical and experimental results are compared to previous calculations and measurements. Recommended electron cross-section datasets are constructed over an incident electron energy range of 0.01–10 000 eV.

Current stage and future development of Belgrade collisional and radiative databases/datasets of importance for molecular dynamics

“…59 This method has been applied for electronic excitations of resonant lines of zinc, 60 lead 61 and most recently cadmium. 62 Molecular dynamics induced by electron impact has been extensively studied. As an example of the low energy dissociative electron attachment process we refer on the case studies of ozone 63,64 where resonant collisions induce formation of atomic and molecular oxygen anions with large cross sections having important consequences for the anion formation processes in the ionosphere.…”
