Triple differential cross sections (TDCS`s) have been calculated for ionization of He{sup +} 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} {ital 1997} {ital The American Physical Society}
