Spectrum of doubly ionised indium

The Third Spectrum of Indium: In III

“…e Number of observed lines determining the level in the optimization procedure LOPT [15]. f Reference to the level source as B, K, R, K+TW, R+TW and TW stand for Bhatia [6], Kaufman et al [7], Ryabtsev et al [9], previous value [7] has been revised, previous value [9] has been revised, and this work ; * stands for levels from [6,7,9] re-optimized in this work. Ki stands for Kilbane et al [8] level values, which have not been included in the level optimization.…”

“…If marked as # then the given gA values are too unreliable for the transitions whose cancellation factor |CF| < 0.10 in our calculations with Cowan's code [12]. i Reference to the source: B-Bhatia et al [6]; B, TW-Wavelength from this work; K-Kaufman et al [7]; R-Ryabtsev et al [9]; S-Skočić et al [10]; TW-this work.…”

“…This work is listed in the Atomic Energy Levels (AEL) compilation [5]. Bhatia [6] investigated the In III spectrum more comprehensively using a 3-m normal incidence vacuum spectrograph in the range 340-2300 Å with a 1200 lines/mm grating giving a reciprocal dispersion of 2.775 Å/mm and a prism spectrograph in the region 2300 Å to 9500 Å with a disruptive electrodeless discharge. He revised and extended the earlier analysis and established the levels of the 4d 10 ns (n = 5-12), 4d 10 np (n = 5-9), 4d 10 nd (n = 5-9), 4d 10 nf (n = 4-7), 4d 10 ng (n = 5-9), 4d 10 nh (n = 6-9), 4d 9 5s 2 , and 4d 9 5s5p configurations.…”

“…As mentioned above, a number of publications on In III appeared in the literature [1][2][3][4][5][6][7][8][9][10][11]. Among these, Bhatia's [6] analysis was the most comprehensive and contained a large number of one-electron configurations.…”

“…Among these, Bhatia's [6] analysis was the most comprehensive and contained a large number of one-electron configurations. However, after careful examination of these results, a number of irregularities were noticed in Bhatia's results, for example, many lines classified did not match the In III characteristics on our recorded spectra and 17 reported lines have incorrect conversion between wavenumbers and wavelengths.…”
