Abstract
Self‐consistent field calculations of the dipole polarizability tensor of diatomic helium at four internuclear separations between 4a0 and 6a0 are reported. For larger separations, the calculations are shown to reduce to the point‐dipole model of long‐range polarizabilities. The computed polarizability is used in a companion paper to obtain estimates of the second dielectric constant virial coefficient, the Kerr constant virial, and the spectral moments for Raman scattering.Keywords
