Description

The aim of this work is to compute the momentum transfer cross section and to investigate the influence of various approximation on it. Present results are based on the many-body theory, namely, the random phase approximation with exchange (RPAE) with and without the inclusion of the virtual positronium formation (VPF) effect.
