Description
Triple differential cross sections (TDCS's) have been calculated for ionization of He+ by electron impact in the coplanar asymmetric geometry for three different incident energies 250, 500, and 1000 eV, and fixed value of the ejected energy 5 eV and scattering angles (4 degree and 10 degree), and in the coplanar symmetric geometry for incident energies of 250 endash 2000 eV as well. The final-state wave function used here considers all three two-body interactions and satisfies the proper asymptotic Coulomb boundary condition. The initial channel wave function involves a Coulomb wave due to the long-range Coulomb attraction between the incident electron and the screened ionic nucleus. Parts of the calculated TDCS's are compared with the existing theoretical results. copyright 1997 The American Physical Society
