Electron interactions with beryllium and its hydrides

Abstract

In present study of electron driven inelastic processes, we report calculated probabilities of inelastic events (including total inelastic and ionizations) occurrence by quantifying the cross sections, $Q_{inel}$ and $Q_{ion}$ for beryllium (Be) and beryllium hydrides viz. BeH, BeH₂, Be₂H₂ and Be₂H₄ from the molecular ionization threshold to 5 keV. The Spherical Complex Optical Potential (SCOP) to compute $Q_{inel}$ has been employed and $Q_{ion}$ is extracted using Complex Scattering Potential –ionization contribution (CSP-ic) approximation. Owing to the toxic character of beryllium compounds we do not find any experimental work for these molecules. In paucity of the experimental data, present work is important and will fill the void of the data needed for particular in plasma physics, aero science, astrophysics and chemical analysis. This study is the maiden report of $Q_{inel}$ for all of these important targets.
