Ionization Cross Sections by Electron Impact of Halogen Atoms, Diatomic Halogen and Hydrogen Halide Molecules
M A. Ali, Yong Sik Kim
The Binary-Encounter-Bethe (BEB) model has been applied to calculate electron impact ionization cross sections of Br, I, Br2, I2, HCl, HBr and HI. The BEB single ionization cross sections of Br and I presented here and also of Cl and Cl2, as reported previously by us, agree generally well with experimental results with respect to low and high energy behavior and peak values. In view of this general good agreement, the BEB cross sections of the other molecules, for which no experimental results are available, are also expected to be reliable. We compare our results with those from alternative models, where available. We also explore the use of effective core potentials for the heavy atoms for these molecules within the context of the BEB model.
