Energy calculation for excited lithium atom in position space

الملخص EN

The energy expectation values (E) for Li and Li-like ions (Li, Be+ and B2+) have been calculated and examined within the ground state (1s 2s α)2S and the excited state (1s 3s α)2S in position space.

The partitioning technique of Hartree-Fock (H-F) has been used for existing wave functions.
