Hyperfine structure in the arc spectrum of xenon. II

Abstract

Since an earlier publication (Jackson & Coulombe 1972) concerning hyperfine structure in the arc spectrum of xenon many new measurements of these structures have been made in connexion with observations of isotope shifts; measurements have also been made of the hyperfine structures of a number of lines not previously investigated. Tables are given of the revised values and of the new values of the hyperfine structures and of the hyperfine structure constants A of the levels of 129 Xe and A and B of the levels of 131 Xe. The good agreement of the experimental values of the A constants for the levels of 129 Xe and 131 Xe with the values calculated by Liberman (1969, 1971) is not altered by the revised experimental values, while it is improved for the B constants of 131 Xe. The average of the ratios of the A constants of five levels of 129 Xe and 131 Xe given by the revised and the new values is —3.376 + 0.02, differing by 0.002 from the previously published value and by —0.001 from the ratio found from nuclear resonance measurements (Faust & McDermott 1961).
