Static Polarizabilities of Helium and Alkali Atoms, and Their Isoelectronic Ions

A rather simple method of calculation of the scalar and tensor components of static polarizability was developed for a wide range of atoms and ions. The general formulas for polarizabilities of SL terms, J levels, and F components of hyperfine structure are given. The results of calculation for ground and some excited states of He and alkali atoms (Li, Na, K, Rb, Cs) are presented. The comparison of the results with available theoretical and experimental data shows that, in most cases, the differences do not exceed 10%. The polarizabilities for the Li+, Be+, B2+, C3+, Ne7+, Mg+, Al2+, Si3+, Ar7+, Ca+, Sc2+, Ti3+, Sr+, and Ba+ ions are also given.
