Abstract:

Nonrelativistic energies of the 21S and 23S states of He, Li, and Be and the 31S and 33S states of He and Li have been calculated by the Rayleigh-Ritz variational method. Mass polarization corrections have also been evaluated. After correction for mass polarization, relativistic, and electromagnetic shifts the energies calculated with 31-term expansions differ from experimental values by about 2 or 3 reciprocal cm for singlet, and about .4 reciprocal cm for triplet, states. The relative effectiveness of expansions involving one, two, and three exponential parameters is discussed. For excited singlet S states, expansions with three exponential parameters result in a considerably better energy than expansions with two such parameters. Author
