Abstract
The variation-perturbation method previously used in the calculation of dynamic polarizabilities of the hydrogen atom and long-range dispersion energy coefficients between hydrogen atoms is applied, within the framework of uncoupled Hartree-Fock perturbation theory, to the dipole and quadrupole polarizabilities of the hellium atom. It is shown that simple first order wavefunctions built up from Slater-type 2p and 3d orbitals with optimized frequency-dependent exponents yield quite accurate values for the dynamic polarizabilities of the helium atom and for the long-range dispersion energy coefficients.
