Elastic cross-section calculations for electron collisions with XY 4 (X=Si, Ge; Y=H, F, Cl, Br, I) molecules

Abstract

We report calculations of integral cross-section and differential cross-section for intermediate- and high-energy (20–2000 eV) elastic electron collisions with tetrahedral compounds of silicon and germanium: SiH 4, SiF 4, SiCl 4, SiBr 4, SiI 4, GeH 4, GeF 4, GeCl 4, GeBr 4 and GeI 4. The calculations have been carried out using an independent atom model with static-polarization model potential. The present results are compared with available experimental and theoretical data. For collision energies higher than 100 eV, results of present theoretical calculations are in satisfactory agreement with experimental data.
