Theoretical Study on the $K_{}\alpha}$ Transition Properties of F-Like Ions

“…This is attributed to the contributions of relativistic effect which is larger with increasing Z. Furthermore, it is obvious that the present calculations are in better agreement with both the experimental measurements [12,19,27] and the NIST results [28] than the computations of Sur et al [9] . It has been turned out by Dong et al [29] that both Breit interaction and QED effects contribute much to the binding energies of the highly charged ions, especially for the few electrons system, and this will further influence the transition energies among different levels.…”

“…F-like ions can give rise to K α transition when there is a vacancy in K shell. Many studies have been done for F-like ions in both experimental observations and theoretical calculations [1,[8][9][10][11][12][13][14][15][16][17][18][19], but most of these works focused on spin-orbit intervals in the ground states. Therefore, it is necessary to perform a comprehensive theoretical research on F-like ions, including the ground-state fine structures, K α transition energies and probabilities.…”

EUV measurements of Kr XXI–Kr XXXIV and the effect of a magnetic-dipole line on allowed transitions

“…For example, x-ray spectroscopy has been performed at the Lawrence Livermore National Laboratory (LLNL) and the National Institute of Standards and Technology (NIST) electron beam ion traps (EBITs) [4][5][6] and the GANIL accelerator [7]. Extreme ultraviolet (EUV) and x-ray transitions of krypton have also been studied on a variety of devices, such as the JET tokamak [8], the PITHON relativistic electron beam [9], EBITs [6,10], and beam foil machines [11]. Highly ionized krypton in the visible range has been studied on the LHD stellarator [12] and the NIST and LLNL EBITs [13,14].…”
