“…The WBEPMT and QDO theory, which can be used to calculate the lifetimes for both highly excited states and low-lying states without any increase in complexity in calculation process have a simple calculation procedure. Previously, much spectroscopic data, such as transition probabilities, oscillator strengths, lifetimes of excited levels, and ionization energies were obtained by using the WBEPMT and QDO theory in many-electron atomic and ionic systems [21][22][23][24][25][26][27]. The semiempirical methods, such as the WBEPMT and QDO theory, where one or more parameters needs to be adjusted according to the existing accurate data can be considered as a useful method for much more complicated systems, especially for highly excited states.…”

The lifetimes of some excited levels for singly ionized nitrogen are calculated by using the weakest bound electron potential model theory and quantum defect orbital theory. We determined expectation values of radii using numerical nonrelativistic Hartree-Fock wave functions. The necessary energy values have been taken from NIST. The present results have been compared with previous calculations and experiments. Most of the lifetime results are presented for the first time in the present work. For N II, because there are few lifetime results available in the literature, the present study compared to existing investigations, provides detailed results for the lifetimes of several of the excited 2s 2 2pns, 2s 2 2pnp, and 2s 2 2pd ¡ 2s 2 2p 2 where, n = 3-6 for the ns series, n = 3-5 for the nd series and n = 3-4 for the np series.Résumé : Nous calculons les temps de vie de certains niveaux excités de l'azote ionisé une fois, en utilisant la théorie du potentiel de l'électron le moins lié et la théorie d'orbitale à défaut quantique. Nous déterminons les valeurs moyennes des rayons, en utilisant les fonctions d'onde numériques de Hartree-Fock non relativiste. Les valeurs d'énergie requises sont celles du NIST. Nous comparons nos résultats avec des résultats de calculs antérieurs et avec des résultats expérimentaux. La plupart des temps de vie présentés sont publiés pour la première fois. Puisqu'il y a peu de résultats disponibles pour N II dans la littérature, ce travail, comparé à d'autres études, fournit des résultats détaillés pour les temps de vie des états excités 2s 2 2pns, 2s 2 2pnp et 2s 2 2pd ¡ 2s 2 2p 2 , où n = 3-6 pour les séries ns, n = 3-5 pour les séries nd et n = 3-4 pour les séries np.[Traduit par la Rédaction]

“…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].…”

Rydberg physics is the most exquisite playground for the exploration of quantum technologies. Therefore, in this spectral investigation based on weakest bound electron potential model theory (WBEPMT). The quantum defects and Rydberg energies of low-lying and high-lying spectral Rydberg energy sequence in the following configurations: 1s2ns2Se1/2 and 1s2np2Po1/2 in Lithium-like ions (Z=4-6) Beryllium (Be II), Boron (B III) and Carbon (C IV) are computed with their radial expected values. Total 43 low-lying energies and quantum defects are computed and compared with 25 low lying radial expected values. The results are in good agreement with the previously published experimental / theoretical results. Based on the good agreement of low-lying data, total 257 new values of high-lying Rydberg energies and quantum defects are computed with 575 radial expected values currently not listed at NIST. The deviation in both sets of data doesn’t exceed 1 cm-1 .

Theoretical computations of Rydberg energy levels series and atomic lifetimes for singly ionized boron (B II), silicon (Si II), and germanium (Ge II) have been performed. In the theoretical computation weakest bound electron potential model theory (WBEPMT) is employed. Regularities of changes in quantum defects for the following Rydberg states series: 2sns (1S0), 2snp ([Formula: see text]), 2snf ([Formula: see text], [Formula: see text], [Formula: see text]), 2snf ([Formula: see text]) of B II; 3s2ns (2S1/2), 3s2nd (2D3/2,5/2), 3s2nf ([Formula: see text]), 3s2ng (2G7/2,9/2) of Si II; and 4s2nf ([Formula: see text]), 4s2nf ([Formula: see text]), 4s2ng (2G7/2,9/2) of Ge II, up to n = 50 are presented. The atomic lifetimes of the following series: 1s22sns (1S0), 1s22snp ([Formula: see text]), 1s22snd (1D2) of B II; 3s2ns (2S1/2), 3s2nf ([Formula: see text]) of Si II; and 4s2ns (2S1/2) of Ge II are predicted with good accuracy. Some high-lying Rydberg energy levels and atomic lifetimes have been presented for the first time. The series for which Rydberg energy levels are computed in this work are unperturbed series.
