Abstract
Total cross sections (TCS) and single differential cross sections (SDC S) have been computed for the single ionization of the ground state of helium by electron impact in a distorted wave formalism which takes i nto account the effects of the initial and final channel distortions. The present TCS and SDCS results are in fair agreement with the measur ed values and other theoretical predictions for the incident electron energy E(i) > 150 eV.
