Inclusion of Neighboring atom effects in average atom calculations, use of multiple scattering theory

We present here an attempt to include the effects of neighboring atoms within the framework of the self-consistent average atom procedure. Multiple scattering formalism developed for the study of liquid metals and amorphous materials is used to describe the effect of the adjacent scatterers in dense plasma problems. The influence of a single nearest neighbor on the density of states of the 2p resonance in highly compressed aluminium is investigated. The multiple scattering formalism is incorporated into a full self-consistent average atom calculation, this procedure is discussed here in detail. The pressure using this procedure is compared to that obtained using the LMTO method
