Using `Dressed' Convoluted Quasi-Sturmian Functions as a Basis for Coulomb Three-Body Continuum Problems

Abstract

Synopsis We present an ab initio approach to the two electron continuum problem based on an expansion on convoluted quasi Sturmian functions (CQS) equipped with an appropriately built electron-electron phase factor. Such'dressed' CQS functions constitute a suitable basis to solve Coulomb three-body scattering problems as illustrated through numerical applications to double ionization processes on Helium. They put in evidence, once more, the importance of electron-electron correlation over the whole space.
