Differential ionization cross-section of hydrogen bromide

Abstract

In this study, the relative single and double differential ionization cross-section of the hydrogen bromide molecule and their fragmented ions (HBr+, Br+, H+) have been theoretically evaluated. In the single differential ionization cross-sections, the loss of incident electron energies (W) at 100 eV, 200 eV, and 500 eV is calculated. The double differential ionization cross-section of the HBr molecule is determined for secondary electron energy (e) and different incident scattering angles (θ). The differential ionization cross-sections of the hydrogen bromide molecule were investigated for the first time.The derived results of the HBr molecule are not only important in spectrometry but may also be interesting for atmospheric sciences.
