The momentum transfer dependence of the cross section for electron impact ionization of helium for (e,2e) process is investigated by use of BBK model and modified BBK model. The results of the present work are compared with experimental data. The structure of the cross section is analysed, and the effective shield is discussed in detail in the final state.
