Electronic Structure of AC-Clusters and High-Resolution Xray Spectra of Actinides in Solids

Abstract

AbstractAb initio calculations using SCF approach for and analysis of results of investigation of the electronic structure of the clusters RA+n:[L]k with rare earths or actinides were carried out for the clusters in solids and liquids. Theoretical results for the electronic structure, radial integrals and energy of X- ray lines are presented for AC ions with unoccupied 5f-shell in the clusters in oxides, chlorides and fluorides environment. Possibility of collaps of nf-shell for the separate clusters and identification of electronic state of ions with unstable nuclei, are discussed, too.
