Abstract
A procedure is presented that uses perturbation theory to calculate correlation corrections for atomic polarizability when the atom is described by a local potential in the starting approximation. Zeroth-order polarizabilities and first-order correlation corrections for them have been calculated for Mg, Na, Ne, Be, Li, and He atoms using the Hartree-Fock-Slater potential and another local potential. For most of the atoms, the corrections are found to be significantly large. Implications are discussed.Keywords
