Electric dipole transition probabilities, oscillator strengths, and lifetimes for Co16+

The electric dipole transition probabilities, oscillator strengths, and lifetimes for Co16+ have been calculated within the weakest bound electron potential model (WBEPM) theory using experimental energy levels and theoretical expectation values of orbital radii corresponding to those energy levels under the assumption of the LS coupling scheme. In the calculations both multiplet and fine structure transitions are studied. The present results are consistent with earlier results given in the literature. Moreover, some transition probability and oscillator strength values not existing in the literature are reported for the first time.

Energy levels of the 5d3/2nf, 6p3/2nd autoionizing series of Hg I

In this paper, three autoionizing Rydberg series energy levels [Formula: see text] (n = 5–20), [Formula: see text] (n = 6–20), and [Formula: see text] (n = 6–20) for Hg I are calculated using the WBE potential model (WBEPM) theory, considering foreign level perturbation corrections. The theoretically calculated results are in good agreement with present known experimental data, and some energy levels of these three series without experimental values are predicted.

Oscillator strengths and transition probabilities for singly ionized terbium

Electric dipole transition probabilities and oscillator strengths for singly ionized terbium (Tb II) have been calculated with the weakest bound electron potential model (WBEPM) theory using experimental energy levels and theoretical expectation values of orbital radii corresponding to those energy levels under the assumption of the Jj coupling scheme. The transition probabilities and the oscillator strengths calculated have been compared with available data in the literature. A good agreement has been obtained. In this work, the WBEPM theory has been applied to heavy atoms, such as Tb II, for the first time.
