Calculations with spectroscopic accuracy for energies, transition rates, hyperfine interaction constants, and Landé g -factors in nitrogen-like Kr XXX

Benchmarking calculations of excitation energies and transition properties with spectroscopic accuracy of highly charged ions used for the fusion plasma and astrophysical plasma

“…Using at least one of the three methods (RMBPT, MCDHF, and FAC-RCI), we carried out many theoretical studies of excitation energies and E1, M1, E2, M2 transition rates for Kand L-shell ions with Z ≤ 42, such as the ions in the sequences of H-like, [37,38] He-like, [39,40] Be-like, [41][42][43][44][45] B-like, [46][47][48] C-like, [49,50] N-like, [51][52][53][54][55] Olike, [56][57][58][59][60] F-like, [61][62][63] and Ne-like. [64] It is important to provide atomic data for more than just the levels of the lowest configurations in plasma modeling and diagnostics.…”

Excitation of Some Nitrogen-Like Ions: Calculations and Comparison with Measurements

“…As for the ground state of boron-like and carbon-like ions [15], [16], [17], the energy of the ground state of nitrogen-like ions, 1s22s22p3, is described assuming the formation of a hybrid state of all (five) 2s22p3 outer electrons with the identical wave function parameter. The interaction potential of 2s electrons and 2p electrons with internal 1s electrons is described in the same way as in lithium-like ions [18][19][20][21][22].…”

Benchmarking Atomic Data from Large-scale Multiconfiguration Dirac–Hartree–Fock Calculations for Astrophysics: S-like Ions from Cr ix to Cu xiv

“…The other aim of the present study is to offer a consistent set of transition rates with high accuracy for all the ions for spectral line modeling. This study is an extension of our previous calculations (Jönsson et al 2011(Jönsson et al , 2014Wang et al 2014Wang et al , 2015Wang et al , 2016aWang et al , 2016bWang et al , 2017aWang et al , 2017bWang et al , 2017cWang et al , 2017dWang et al , 2018aWang et al , 2018cGuo et al 2015Guo et al , 2016Si et al 2016Si et al , 2017Chen et al 2017Chen et al , 2018Zhao et al 2018) for offering atomic data with high accuracy for L-and M-shell systems.…”
