Finite perturbation calculation for the static dipole polarizabilities of the atoms Na through Ca

Abstract

Static dipole polarizabilities are calculated from pseudonatural orbital configuration expansion wave functions for the ground states of the atoms Na through Ca with an accuracy estimated to about 2%. The resulting values are (in the order Na-Ca) 165.02, 71.32, 56.27, 36.32, 24.52, 19.60, 14.71, 11.096, 287.6, and 153.9 a.u. The influence of the electron correlation on the polarizabilities is shown to reflect its influence on the radial distribution of the electrons.
