“…In the footnotes the references are explained. Among these, TW stands for the present work whereas the others originate from earlier experiments, such as the accurate measurements of Edlén [6] and Ölme [8] and the reliable beam-foil data obtained by Dumont et al [11] and Baudinet-Robinet et al [12]. The early beam-foil study of Berry and Subtil [10] also includes valuable data, but the uncertainties are larger.…”

“…Jannitti et al [25] observed several lines of core-excited B III in absorption using the dual laser-produced plasma technique. Based on all these observations and calculations of Bruch et al [24], 10 optical transitions within the core-excited doublet system of B III have been identified [12,19,20]. In 1997 one of us, ANR, made a detailed and thorough critical compilation of the energy levels of B III, which has not been published till now.…”

“…He also provided more accurate energies for many levels up to n = 5 and 6. Additional data for levels in the 1s 2 nl 2 L system were presented in some beam-foil articles [9][10][11][12]. Litzén and Kling [13] precisely measured the 2s-2p lines of the two boron isotopes, 10 B and 11 B, using Fourier transform spectroscopy of a hollow-cathode discharge.…”

“…However, their proposed assignments had to be revised later, because initially there were no accurate calculations available to guide the identification work. However, after extensive configuration-interaction calculations by Chung et al [18], experimental work made fast progress [12,[19][20][21]. More than 50 transitions between core-excited quartet states were identified in the region 300-6130 Å.…”

We have undertaken the study of the Li-like spectrum of doubly ionized boron, B III. The spectroscopic data have been obtained with beam-foil spectroscopy and high-resolution spark spectroscopy. The experimental work was combined with theoretical calculations using ab initio and semi-empirical techniques. About 50 new transitions have been observed, and most of the previously known lines have been measured with improved accuracy. We have also critically evaluated all previous and recent data for this spectrum. Complete data on wavelengths and energy levels based on this analysis are tabulated.

“…With a transition probability of 293.2-10 s s-1 we would certainly confirm that 2p24P-2p4d4D ° should be a strong line in the quartet spectrum of NV. On the other hand, our calculated transition probability The 2p4d4p°-4D ° energy separations for ions in the lithium sequence have been reported by several authors [1,15,16] and results are assembled in Table 4. It may be observed that only for the N V ion is there gross disagreement between the experimental and theoretical values.…”

Energies and structures of ls2snl4L and ls2pnl'4L core-excited levels in lithium-like NV are calculated. Wavelengths, transition probabilities and radiative lifetimes are reported and compared with available experimental data. It is suggested that the 1 s2p4d4P °, 4D° levels are nearly degenerate in NV and have not been resolved experimentally. Several new assignments for observed lines are proposed.

Optical studies of multiply-excited states are reviewed with emphasis on emission spectroscopy. From optical measurements, properties such as excitation energies, lifetimes and autoionization widths can be determined with high accuracy, which constitutes a challenge for modern computational methods. This article mainly covers work on two-, three- and four-electron systems, but also sodium-like quartet systems. Furthermore, some comments are given on bound multiply-excited states in negative ions. Fine structure effects on transition wavelengths and lifetimes (autoionization) are discussed. In particular, the most recent experimental and theoretical studies of multiply-excited states are covered. Some remaining problems, which require further attention, are discussed in more detail.
