Abstract

The static dipole, quadrupole, and octupole polarizabilities of heliumlike ions are calculated for the $1 s 2 p^{1} P$ and $1 s 2 p^{3} P$ states with $Z$ up to 10, using variational wave functions in Hylleraas coordinates. A general sum rule for the $2^{l}$ -pole oscillator strengths is derived.
