Correlated electron-pair properties of the Be atom in position and momentum spaces

Abstract

application/pdfBased on multiconfiguration Hartree–Fock calculations, correlated electron-pair intracule (relative motion) and extracule (center-of-mass motion) properties are reported for the Be atom in position and momentum spaces. Particularly in the latter space, the present results are more accurate and consistent than those in the literature.journal articl
