Abstract
Static electric polarizabilities were calculated for the 10-electron isoelectronic series OH-, F-, NeH+ and Mg2+ in the LCAO-SCF-MO approximation. All the independent components of all polarizability tensors up to the fourth rank were included in the study. The isotropic components of the fourth order polarizability tensors C, B and γ are, in atomic units, Ȼ = 69.10, 35.19, 1.79 and 0.24, Ƀ = -2286, -552, -6 and -0.3 and = 94600, 12900, 24 and 0.6 for OH-, F- NeH+ and Mg2+, respectively.
