Analytical potential for determining atomic properties of ions in plasmas for a wide range of plasma coupling parameters. An application to calculate total photoionization cross section

Abstract

In this work we propose a model for obtaining an effective atomic potential which includes interaction of the bound electron of the ion with the plasma surrounding, for a wide range of plasma coupling parameters. The potential has been developed considering free electrons charge distribution in the neighbourhood of the ion, linearized Boltzmann charge distribution for free electron and ions at medium and large distances of the nucleus and the reaction of the plasma-charge density to the optical electron in a relativistic quantum state (nlj). An analytical expresion for this non isolated potential is proposed.
