The triple differential cross sections for electron impact ionization hydrogen (e, 2e) reactions are calculated as an example by use of the impulse approximation and Born approximation model at different coplanar asymmetric geometries. The results of the present work are compared with experimental data. The structures of the cross sections and the physical nature of these structures are discussed in detail. Moreover, the exchange effect contribution to the cross section is also discussed, which supports our earlier conclusions.
