Abstract: A correlated three-body continuum wave function proposed by Brauner et al. has recently been modified further to allow for the three-body effects by introducing Sommerfeld parameters (Berakdar and Briggs),it is used to calculate the triple differential cross sections for electron impact ionization of He+ in coplanar equal-energy sharing and symmetric geometry. The initial channel wave function involves a Coulomb wave function due to the long range Coulomb attraction between the incident electron and the screened ionic nucleus. Since the present work deals with symmetric collisions, the electron exchang effect between the two continuum electrons has been taken into account properly. It is shown that the initial channel Coulomb field play a major role in determining the triple differential cross sections at near-threshold incident energy and small impact parameter values.
