The theoretical lifetimes for singly ionized beryllium (Be II) have been calculated using the weakest bound electron potential model theory and the quantum defect orbital theory under the assumption of the LS coupling scheme. In the calculations, many states are considered. Some lifetime values for highly excited levels have been obtained using these methods. The lifetimes presented in this work have been compared with the early theoretical calculations and measurements presented in the literature. A good agreement with the results in the literature has been obtained.

“…Some atomic or ionic properties in multielectron systems, such as transition, excitation, and ionization, may be referred to the WBE's behavior. The treatment of WBE gives some accurate information about these properties in many cases [13][14][15][16][17].…”

“…The WBEPMT was developed by Zheng et al [13] and has been applied for determination of some physical parameters, such as energy levels, ionization potentials, transition probabilities, oscillator strengths, and lifetimes of excited levels in many-electron atomic and ionic systems [13][14][15][16][17]. Zheng suggested a new model potential to describe the electronic motion in multielectron systems and separated into two groups for electrons within a given system, the weakest bound electron (WBE) and the nonweakest bound electrons (NWBE).…”

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]

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.
