Abstract

Calculations of the static electric-dipole scalar and tensor polarizabilities are presented for two alkali-metal atoms, Rb and Cs, for the $n S, n P_{½, 3 / 2}$ , and $n D_{3 / 2, 5 / 2}$ states with large principal quantum numbers up to $n = 50$ . The calculations are performed within an effective one-electron approximation, based on the Dirac-Fock Hamiltonian with a semiempirical core-polarization potential. The obtained results are compared with those from a simpler semiempirical approach and with available experimental data.
