Abstract

Synopsis: The driven equation describing an ( e, 3 e ) process on helium in the framework of the Temkin-Poet model is solved numerically using expansions of Convoluted Quasi Sturmian functions. As we observe first that the convergence rate of the solution is rather poor, we propose to significantly improve the expansion by introducing a phase factor corresponding the electron-electron interaction into the basis functions.
