摘要：

Calculation for electron impact total ionization cross sections on halogen atoms (F, Cl, Br and I) and their hydrides (HF, HCl, HBr and HI) are performed employing Spherical Complex Optical Potential and Complex Optical Potential-ionization contribution formalisms. In this article we are presenting data for energies ranging from above threshold to 2000 eV. Our results are compared with available experimental and theoretical data wherever available. It is found that the present result gives a better account of the ionization cross sections. (C) 2010 Elsevier B.V. All rights reserved.
