摘要：

The double differential cross sections for electron impact ionization of hydrogen at incident energies of 15.6 eV, 17.6 eV, 25 eV and 40 eV are calculated by use of BBK model and modified BBK model. The results of the present work are compared with the absolute experimental date. The structure of the cross sections is analysed and the contributions of exchange effects to corss sections are discussed.
