Abstract
The authors report the first measurements of photodetachment cross sections for He- (formed through charge exchange of He+ with Ca vapour) over the photon energy range from 1.77 to 2.75 eV. Uncertainties associated with the electronic configuration of the He- ion are removed by determining the energy of the autodetached electrons. The measured autodetached electron energy agrees with the known (1s2s2p)4P0 He- energy level.Keywords
