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.
