The double differential cross sections for electron impact ionization of helium are evaluated in the framework of a distorted wave approximation that takes into account the effects of initial channel, final channel, and target distortion. The present results are in fair agreement with the measured values and rigorous DWBA (distorted-wave Born approximation) results of McCarthy and Zhang.

We calculate the total and single differential cross sections for the electron impact ionization of the ground state of singly ionized helium at various energies in a distorted wave approximation. Present results are compared with existing theoretical and experimental results. PACS Nos.: 34.80.Dp, 34.50.Fa
