“…The complexity of working with many electron atom have been circumvented in different theoretical investigation [20][21][22][23][24][25] by considering the model potential [26,27], where the effect of the core electrons have not been considered explicitly. The model potential of the alkali atoms initiates the multi-electron core interaction with the single valence electron by an analytic modification of the Coulomb potential.…”

Target ionization processes of alkali atoms by Positronium impact are investigated. Calculations are performed in the frame work of model potential formalism using the Coulomb distorted eikonal approximation. Interesting qualitative features are noted both in the scattered Ps and the ejected electron distributions in triple differential as well as double differential levels of the collision cross sections.

A b s t r a c t . There are several sets of parameters of the often used Hellman-like model potential discussed which had been determined by variational fitting within different basis sets. It is shown that Slater-type orbitals (STO) form a useful variational basis. There are well approximated parameter values obtainable even if only one STO is used. cber die Parameter im Hellniannschen ModellpotentialI n h a l t s i i bersicht. Es werden verschiedene Parilmotersiitze fur &s oft verwendete Hellmannsche hIodellpotential diskutiert, die durch Variationsonpassung mit unterschiedlichen Modellwellenfunktionen bestimnit wurden. Dabei wird gezeigt, daB Slater-orbitale (STO) sehr gut als analytische Variationsfunktionen geeignet sind. Bereits mit einem einzelnen STO ergeben sich befriedigende Niihernngen fiir die Potentialparameter.
