Abstract
The aim of this work is evaluation the expectation values of Correlation , repulsion between electrons ,attraction between electrons and nucleus energies and various one ,two electrons distances and (where d is an integer takes the values -2,-1,+1,+2) for some positive ions C+3,N+4,O+5.By employing the partitioning technique, four Hartree-Fock wave functions are analyzed of K , L shells and for Singlet 1S and Triplet 3S states.
