✦ Synopsis

An acxuate semi-empirical method based on the many-ekctron theory of Sinano@u for calcukting relativistic contributions to atomic energies is developed and applied to the Is', 1~~2s and ls22s2 isoelectronic seiuences in the fist and second periods. Orbital additivity of relativistic energies is tested and found to be an inaccurate assumption for small Z.

Correlation effects are shown to change generalized oscillator strengths and inelr&c form factors by large factors a5 large as 10, from the Hartree-Fock values. The effects are fully included in the charge wavefunctions of the non-closed shell mny-electron theory by Sirmna~u. We calculate ihe charge
