Spectrum of doubly ionized xenon (Xe III)

Abstract

The spectrum of doubly ionized xenon has been investigated. The study is based on photographic recordings of xenon spectra in the 490-8900 Å range. The number of classified lines has been increased from about 300 to about 1400. The lines have been classified as transitions between 73 even levels belonging to the $latex 5s^{2}5p^{4} $, $latex 5s^{2}5p^{3}6p $, $latex 4\\phi $, $latex 5\\phi $ and $latex 5s^{0} 5p^{6} $ configurations, and 83 odd levels belonging to the $latex 5s5p^{5} $, $latex 5s^{2} 5p^{3} 6s$, $latex 7s$, $latex 5d$ and $latex 6d $ configurations. In particular, the classifications include most of the Xe III laser lines. The experimentally observed level structures are compared with the results of Hartree-Fock calculations and least-squares fits. A comparison is also made between the results of the present analysis and the published data on the Xe N$latex_{4,5} OO$ Auger spectrum
