“…In this work, for these B-like ions, the quantumelectrodynamic effect and high-order relativistic corrections for transition wavelengths are about 0.004Å by the formula in Refs. [21,22], which are smaller than the experimental uncertainties. So they are not considered in the wavelength calculations.…”

Energy levels and the radiative and Auger transition rates of the 1s2p 4 2,4 L (L = S, P , D) resonances in the boron isoelectronic sequence are calculated using the saddle-point variation and saddle-point complex-rotation methods. Large-scale wave functions are used to saturate the functional space. Relativistic and mass polarization corrections are included by the first-order perturbation theory. The Auger branching ratios of the important decay channels for these core-excited states are calculated. The reliable transition wavelengths and Auger electron energies are used to identify available x-ray spectra and Auger electron spectra. Identifications of several unknown experimental lines from 1s2p 4 resonances are reported. The total radiative rates and total Auger rates of these 1s2p 4 resonances are also reported and discussed along with the increase of atomic number Z. It is found that the total Auger rates are several orders of magnitude greater than the total radiative rates in these low-Z ions.

“…The resulting term mixing becomes so important that for the molybdenum (Mo) ion, the dominant contributor, and then the dominant character, of two different states is the 1s 2 2p 3 2 P o 3/2 CSF. Recently, the O IV ion has been studied by Dutta and Majumber [48] with the relativistic coupled-cluster method, Jönsson et al [49], with the multiconfiguration Dirac-Hartree-Fock method, and Sun et al [50] using Rayleigh-Ritz variation method with configuration interaction. 6.3.…”

Energy levels, hyperfine interaction constants, and Landé g J -factors are reported for n = 2 states in beryllium-, boron-, carbon-, and nitrogen-like ions from relativistic configuration interaction calculations. Valence, core-valence, and corecore correlation effects are taken into account through single and double-excitations from multireference expansions to increasing sets of active orbitals. A systematic comparison of the calculated hyperfine interaction constants is made with values from the available literature.

“…For the 6 P e,o (m) (m=1-5) series, the configuration structures are identified by similar method. Furthermore, formulae (15)(16)(17) indicate the fine structure splittings rely on the orbital and spin angular moments, so the assigned configuration structures of these 6 P e,o series could be further determined by the fine structure splittings. The fine structure splittings of 6 P e,o (m) (m=1-5) sextet states of Na 6+ ion are given in the last two columns of Table 1.…”

The energies, fine structure splittings, transition rates, and lifetimes of inner-shell excited sextet states 1s2s2p2nl, (n = 2–7; l = s, p, d) and 1s2p33p of the boron isoelectronic sequence (Z = 8–13) are investigated using the multi-configuration Rayleigh–Ritz variation method. The mass polarization effect and relativistic corrections are included by first-order perturbation theory. Configuration structures of the high-n inner-shell excited sextet series 6Se,o(m) and 6Pe,o(m) (m = 1–5) of boron-like Na6+ ion are assigned. The wavelengths and transition rates of electric-dipole transitions between 6Pe(m) and 6Po(m) (m = 1–5) states are calculated. The quantum electrodynamics (QED) effects and higher order relativistic corrections are also considered to obtain more accurate transition wavelengths. The predicted transition wavelengths agree well with the available theoretical and experimental data. The lifetimes for the inner-shell excited sextet states 6Pe(m) (m = 1–5) are also reported and discussed with the increase of nuclear charge number, Z. These theoretical data are useful for the identification of spectral lines in experiments and the design of XUV and soft X-ray lasers.
