Abstract

The present Proposal focuses on positronium (Ps) scattering by molecules. The theoretical formulation of this problem is the subject of intense research and usually relies on linear combinations of amplitudes for electron and positron scattering. We propose to study available models for non-relativistic deuteron scattering to develop improved models for Ps collisions. In a subsequent step, compotation models might well be developed. (AU)
