Abstract :
The purpose of the present work is to calculate the expectation value of potential energy for different spin states (ααα ≡ βββ,αβα ≡ βαβ) and compared it with spin states (αββ , ααβ ) for lithium excited state (1s2s3s) and Li- like ions (Be+,B+2) using Hartree-Fock wave function by partitioning techanique .The result of inter particle expectation value shows linear behaviour with atomic number and for each atom and ion the shows the trend ααα ααβ αββ αβα.
