The Spectrum of Doubly Ionized Tungsten (W III)

The spectrum of doubly ionized tungsten (W III) was produced in a sliding-spark discharge and recorded photographically on the NIST 10.7-m normal-incidence vacuum spectrograph in the 600-2680 Å spectral region. The analysis has led to the establishment of 71 levels of the interacting 5 , 5 6 and 5 6...

Description
Summary:The spectrum of doubly ionized tungsten (W III) was produced in a sliding-spark discharge and recorded photographically on the NIST 10.7-m normal-incidence vacuum spectrograph in the 600-2680 Å spectral region. The analysis has led to the establishment of 71 levels of the interacting 5 , 5 6 and 5 6 even configurations and 164 levels of the interacting 5 6 and 5 6 6 odd ones. A total of 2636 lines have been classified as transitions between the 235 experimentally determined levels. Comparison between the observed levels and those calculated from matrix diagonalizations with least-squares fitted parameters shows an rms deviation of ±87 cm for the even configurations and ±450 cm for the odd ones.
