Rydberg states of the helium atom

Deng, Jia; Gilbert, Andrew; Gill, Peter


Using the recently introduced maximum overlap method and Hartree-Fock Perturbation Theory (HFPT), we compute Hartree-Fock (HF) wavefunctions for triplet 1s ns states of the helium atom. Comparison with near-exact results from Nakatsuji's free ICI method reveals that HF theory provides a simple route to accurate energies of these Rydberg states, especially for large n.
