Numerical evaluation for the electron-electron distribution function for the four-electron systems for 1s2 2s2-state by using Hartree-Fock Method

Abstract EN

The electron-electron distribution function f (r12) has been evaluated for 1s2 2s2-state by using Hartree-Fock type wave function for many electron systems (Li-, and Be-atom) where Z = 3, 4 respectively and the inter particle expectation values < rn12 > has been evaluated too.

Expectation values are also evaluated with compression between two ion for each individual electronic shell.
