Abstract

Some radial atomic properties of Be-atom in different excited states (1s² 2s 3s, 1s² 2s 4s, 1s² 2s 5s) (¹s) have been obtained using two electron density function

(r₁,r₂) in order to solve Hartree-Fock equations using slater type orbitals using partitioning technique within the individual electronic shells of different configuration of Be-atom in position space. Radial expectations values for one electron

and two electrons

, correlation coefficients

, electron density at the nucleus

, the nuclear magnetic shielding constant

and The diamagnetic susceptibility

have been calculated for these states of the same atom.
