Static Dipole Polarizabilities for Low-Lying Rovibrational States of HD+

Abstract

Accurate calculations are performed for the static dipole polarizabilities of HD+ in the rovibrational states with both of the vibrational and angular momentum quantum numbers v and L from 0 to 5, by using variationally generated wavefunctions in Hylleraas coordinates. Comparison is made with recently published results. Significant improvements are achieved for the angular momentum quantum number L > 0 excited states by including another independent block to optimize meticulously the intermediate states of unnatural parity.
