Spectroscopic analysis of the configurations 5s5p5d, 5p³and 5s5p6s of Xe VI

Abstract

The spectrum of five times ionized xenon (Xe VI) has been observed in the 270-7000 Å wavelength range. We proposed 18 new energy level values of the 5s5p5d configuration, all the energy level values for the 5p3 configuration and three energy level values of the 5s5p6s configuration. The observed configurations were theoretically interpreted by means of Hartree-Fock relativistic (HFR) calculations and least-squares fit of the energy parameters to the observed levels. The parameter values are compared with results from HFR calculations.

REVISED AND EXTENDED ANALYSIS OF FIVE TIMES IONIZED XENON, Xe VI

“…Their results were not in agreement with the reported data from the subsequent paper on the same subject by Churilov & Joshi (2000). Later, Reyna Almandos et al (2001) used the data from Sarmiento et al (1999) to support their spectral analysis, which only partially agreed with the analysis by Churilov & Joshi (2000), publishing weighted oscillator strengths and lifetimes for this ion. Experimental results on energy levels and transitions were critically compiled by Saloman (2004), rejecting the analysis of Sarmiento et al (1999) and Reyna Almandos et al (2001) in favor of the conclusions of Churilov & Joshi (2000).…”

“…Prior to this work, a number of levels belonging to configurations 5s5p 2 and 5p 3 , as well as 5s 2 nl up to n = 8, were known. Configurations 5s5p5d and 5s5p6s have also been studied, but authors (Sarmiento et al 1999, Reyna Almandos et al (2001 on the one side, and Churilov & Joshi 2000 on the other) disagreed on their conclusions about levels and lines. Table 4 has a complete list of the 88 levels that were classified, described in the LS coupling scheme.…”

“…The level at 232585.5 cm −1 , formerly classified as 5p 34 S 3/2 by Sarmiento et al (1999), has now been reclassified as 2 D 3/2 . We also changed the levels 5p 3 2 D 5/2 and 2 P 1/2 , previously identified by only three lines (Churilov & Joshi 2000), to the new values of 240517 cm −1 and 261029 cm −1 , respectively, based on eight new lines.…”

An experimental and theoretical study of the radiative lifetime and oscillator strength in Xe vi, including corepolarization (CP) effects in the calculation, was performed by Biémont et al (2005).…”

“…Collision-based spectroscopy experiments were performed by Larsson et al (1996) and Wang et al (1996Wang et al ( , 1997aWang et al ( , 1997b to investigate the 5s 2 4f and N > 6 configurations of Xe vi at Uppsala University. Sarmiento et al (1999) performed the spectral analysis for the 5s5p5d, 5p 3 , and 5s5p6s configurations of Xe vi based on experiments conducted at the CIOp's laboratory, Argentina. Their results were not in agreement with the reported data from the subsequent paper on the same subject by Churilov & Joshi (2000).…”
