Abstract

A systematic ab initio study is performed on the ground state static dipole polarizabilities of the 2S+1S, S >1/2, atoms from N to Bi, Cr, Mo, Mn, Tc and Re. The benchmark scalarrelativistic values of the scalar polarizability components are obtained using the coupled cluster method. The spin-orbit configuration interaction calculations are carried out for the anisotropic (tensor) polarizability components of these atoms (except Mn and Tc) that arise from the second-order spin-orbit interaction. The tensor polarizabilities are calculated for the first time and found to increase from 10-5 (N) to 3.8 atomic units (Bi) approximately as the fourth power of the nuclear charge. The simple correlations and implication to magnetic trapping of cold atoms are discussed.
