Abstract: A general method to calculate the triple differential cross sections(TDCS) for electron impact ionization of hydrogen atom,hydrogenicion He+, helium atom and helium-like ion Li+is given by generalizing the theoretical framework developed by Brauner et al. The present TDCS results of H, He+, He and Li+are compared with those of other theoretical models and/or experiment, and good agreements have been found.

Key words: (e,2e), electron impact ionization, triple differential cross sections
