Photodetachment cross sections for He-(4P0)
Description
We report the first measurements of photodetachment cross sections for He- (formed through charge exchange of He+ with Ca vapor) over the photon energy range from 1.77 to 2.75 eV. The energies of autodetached electrons from the metastable He- beam have also been determined for the first time. The autodetached electron energy agrees within experimental error (+-0.25 eV) with the known 1s2s2p)4P0 He- energy level. This taken with measurements for the lifetime of He- infers that charge exchange of He+ with Ca vapor produces 4P0 He-
