Analysis of the 5d86s-5d86p transition array in the fifth spectrum of thallium: Tl V

Abstract

The fifth spectrum of thallium was photographed in the 800-1700 AA wavelength region using a sliding spark and a triggered spark source. Two hundred and ninety-five lines, of which 102 lines show HFS, were classified in this spectrum. All but one level in the 5d86s and all but two levels in the 5d86p configuration have been established. The new observations confirm the earlier analysis of the 5d86p configuration of Tl V. Least-squares fitted parametric calculations, using Slater-Condon parameters, were carried out.
