Abstract
Hylleraas method variational calculations up to 367 terms are reported for the three lowest states of neutral helium with 1D and 1F symmetry. Convergence arguments are presented to obtain new estimates of the exact non-relativistic energies of these states. The reliability of the estimates ranges from 10-6 au in the worst case to 10-9 au in the best case.Keywords
