Atomic calculations. II. Polarizabilities and london force constants for F-, Ne, and Na⁺

Calculations are described for the polarizabilities and London force coefficients for F-, Ne, and Na+. The ground-state wavefunctions are with and without correlation. The perturbing functions are singly and doubly excited configurations, which form a set of pseudostates; the polarizability is then calculated by second-order perturbation theory. The various effects occurring here are considered.
