Abstract
We have operated a high-current hollow cathode in pure neon at pressures from 93 Pa to 173 Pa and measured the branching fractions of Ne II emission lines originating from several 3p, 3d and 4f levels, for which lifetime data were available in the literature. This allowed the determination of transition probabilities for all downward transitions, which included a number of weakintersystem lines. We focused our study on these weak lines, using care to assure correct identifications and accurate intensity measurements, in spite of the presence of other much stronger lines in their vicinity. In contrast to an earlier experiment, we achieved close agreement with a recent multi-configuration calculation.Citation
