Abstract
A summation technique is used to calculate the static dipole electric polarizabilities of molecular hydrogen. The technique requires a complete set of single-particle Hartree–Fock states. The occupied Hartree–Fock orbitals for molecular hydrogen are bound, and the complementary set of Hartree–Fock orbitals all lie in the continuum. Such a basis set permits one to evaluate the required sums by integrating over the excited states. The uncoupled Hartree–Fock model is used to calculate the zero-order terms of the components of the polarizability tensor. The first-order corrections to the components of the polarizability tensor are calculated using double perturbation theory. At the equilibrium internuclear separation, R = 1.4 a0, the static parallel dipole polarizability α‖ and static perpendicular polarizability α⊥ are 0.941 Å3 and 0.728 Å3, respectively, which compare favorably with the values 0.944 Å3 and 0.677 Å3 calculated by Kolos and Wolniewicz using a variation–perturbation method. The results are also in satisfactory agreement with the experimental values.
