CALCULATION OF STATIC POLARIZABILITIES AND HYPERPOLARIZABILITIES FOR THE ATOMS HE THROUGH KR WITH A NUMERICAL RHF METHOD

The static electric dipole polarizabilities and hyperpolarizabilities for different states bf the ground configuration of the atoms He through Kr have been calculated at the restricted Hartree-Fock level using a finite perturbation method. The required field-dependent energy and dipole moment data have been computed with a recently developed numerical MCSCF code for atoms in a static electric field.
