Energy Levels and SpectSSrum of Neutral Helium ((4)He I)

A table of energy levels based on the most accurate observations now available is given for the neutral (4)He atom. The wavelengths contained in a revised list of (4)He I lines from 320 A to 21132 A are also based on the best measurements, over half of them having been calculated from the wavenumber...

Sumario:A table of energy levels based on the most accurate observations now available is given for the neutral (4)He atom. The wavelengths contained in a revised list of (4)He I lines from 320 A to 21132 A are also based on the best measurements, over half of them having been calculated from the wavenumber separations of appropriate levels. Several previously disturbing features of the (4)He term scheme are obviated by the revised level values. In a discussion of the experimental results for this spectrum some comparisons with theory are made.
