Re-evaluation of some lithium dipole properties and dipole-dipole and dipole-quadrupole van der Waals constants

Abstract

Our previous one-centre pseudo-state results for some ground-state Li atom dipole oscillator strength sums, the dipole-dipole dispersion energy constants for the Li-Li, Li-H and Li-He ground-state interactions and the dipole-quadrupole dispersion energy constant for the Li-Li interaction are re-evaluated in the light of a more reliable selection for the resonance dipole oscillator strength of the Li atom. These and some of our previous lithium pseudo-state results are compared with corresponding literature values.
