Abstract
The non-relativistic total energy for 1s3d 1D of helium is estimated from the observed 1s2p 1P-1s3d 1D energy difference and a highly accurate non-relativistic energy for 1s2p 1P to be -2.055 620 67 au, in good agreement with the value of -2.055 620 73 au obtained by Sims et al. (1982) from an ab initio calculation.Keywords
