The electric dipole polarizability tensor of the hydrogen molecule-ion has been calculated variationally over a wide range of internuclear separations, using the accurate two center James (ref. 3) orbital as the unperturbed wavefunction. Our most accurate values, obtained with first order functions containing between three and five variational parameters, are in good agreement with some recent moment function values calculated by Bates (ref. 7).
