Spectrum of five times ionized tin (Sn VI) in the vacuum UV region

Abstract

The spectrum of tin excited in a vacuum spark was recorded in the region 500 – 1500 Å on the 6.65 m normal incidence spectrograph. 110 lines of the 4d85p – 4d85d transitions in the Sn5+ ion in the region 680 – 850 Å have been identified and 52 energy levels of the 4d85d configuration have been established.
