Oscillator strengths and transition probabilities for singly ionized terbium

Abstract

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.

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

“…We presented already in previous papers in details how to obtain these parameters [21][22][23][29][30][31]. In Table 1, the electric dipole transition probabilities and the oscillator strengths among multiplet lines are listed (Table 1 is given in the supplementary material of this paper).…”

Spectroscopic properties of lithium like ions: Prospective elements for quantum computation

“…This method permits one to succeed in obtaining simple expressions of the Rydberg energies and Radial expected values in connection with an understanding of the importance of WBE-NWBE's correlation effects in atoms. The advantages of the WBEPM theory have been demonstrated previously [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. In this paper, this method is applied to the computation of the radial expectation values of Lithiumlike ions (Be II, B III and C IV) with their quantum defects and low-lying and high-lying spectral Rydberg energy sequence in 1s 2 ns 2 S e 1/2 and 1s 2 np 2 P o 1/2 up to n=50 electron's state.…”

“…These S e and P o utilized to write the Schrodinger equation of one electron system [32]. The results obtained within the frame work of WBEPM theory are essentially good and they have deviations of less than 1cm -1 for the allowed transitions discussed in previous literature published [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31].…”

“…In weakest bound electron potential model (WBEPM) theory the ideas of quantum defects, foreign level configuration mixing, spectral Rydberg energy series and dependency of Rydberg states series on azimuthal quantum number was also presented. Based on the hypothetical ideas present in WBEPM theory various analytical investigations were performed for different elements neutral and ionic states successfully [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31].…”
