Energies and Lifetimes of Levels for Doubly Ionized Xenon and Radon

Abstract

We have reported the energies and radiative lifetimes of levels for doubly ionized xenon (Xe III) and radon (Rn III). The calculations have been performed using the general-purpose relativistic atomic structure package based on fully relativistic multiconfiguration Dirac-Fock method. We have compared the results obtained from this work for (Xe III) with previous works in available literature. For (Rn III), there is no data except a few energy levels. Hence, we have presented new values on the energy levels of (Rn III).

Electric quadrupole (E2) and magnetic dipole (M1) transitions for doubly and triply ionized krypton, xenon, and radon

“…There is a good agreement between obtained results and previous work results in literature, and observed values from M1 transitions are better than E2 transitions, in general. Although the transition probabilities and wavelengths for the transitions ns 2 np 4 3 P 2 -3 P 0 and ns 2 np 4 3 P 2 -1 S 0 are somewhat poor, in particular E2 transitions, the energy values of these levels reported in our previous work[18] have good agreement with comparison values (n=4, 5, and 6, for Kr III, Xe III, and Rn III, respectively). For Kr III, the energies of levels from this study are 0.04666 Ry and 0.29041 Ry[18] whereas comparison values are 0.04640 Ry and 0.28620 Ry [9] for 3 P 0 and 1 S 0 , respectively.…”

“…Because of the best results have been obtained according to CC correlations, only these results in here have been presented for six ions. Also we reported energies, lifetimes and electric dipole (E1) transition parameters, for these ions [16][17][18]. Other work values are indicated below the tables with a superscript lower case.…”

“…For Rn III and Rn IV, only Biémont and Quinet presented a study about forbidden transition parameters [15]. Also we reported electric dipole (E1) transition parameters, energies and lifetimes for these ions [16][17][18].…”
