Electric quadrupole transition probabilities for singly ionized magnesium

Tune-out and magic wavelengths, and electric quadrupole transition properties of the singly charged alkaline-earth metal ions

“…It is reflected in the table that, in general our evaluated data is in very good agreement with the available literature except for a few discrepancies discussed next. For the 3P 3/2 − 3P 1/2 transition a good agreement of our value is seen with [55] and [56], whereas a small discrepancy can be noticed with the MCHF results in Ref. [57].…”

“…However, our evaluated results for these transitions are in excellent agreement with the WBEMPT calculations by Celik et al [55], RCC calculations by Majumder et al [56] and MCHF calculations by Fischer et al [57], which expresses the reliability in our calculations for these transitions despite of differences with NIST database. Celik et al [55], Majumder et al [56] and Fischer et al [57] have also provided calculations of transition probabilities of many other transitions. It is reflected in the table that, in general our evaluated data is in very good agreement with the available literature except for a few discrepancies discussed next.…”

“…A few groups have studied the quadrupole transition probabilities for Mg + , Ca + , Sr + and Ba + alkaline-earth metal ions using relativistic and non-relativistic methods. The weakest bound electron potential model theory (WBEMPT) calculations of Celik et al [55], the RCC calculations by Majumder et al [56] and non-relativistic multi-configuration Hartree-Fock calculations by Fischer et al [57] have provided quadrupole transition probabilities of the Mg + . The semi-empirical core-potential calculations for Ca + , Sr + and Ba + are provided by Filippin et al [58] for the ground state to metastable state transition probabilities.…”

E1 and E2 transitions for Fe XVI, Co XVII and Ni XVIII

“…The reliable of atomic and ionic structure calculations made using the WBEPM theory, a semi-empirical method based on fitting parameters such as energies and orbital radii, depend on the accuracy of these parameters. Previously, accurate electric dipole and electric quadrupole transition probabilities were calculated using this theory for some multi-electron atoms and ions and it was obtained the good results (Çelik et al 2012a, 2012b, 2014Ateş 2007, 2008;Çelik 2007). In our recent work (Çelik et al 2015), we have shown that the WBEPM theory produces reliable the electric dipole transition probabilities and oscillator strengths for Co 16+ .…”

“…The electric quadrupole transition probability A E2 (in s −1 ) for a transition between two states within the LS coupling in the customary manner is given by (Majumder et al 2004;Çelik et al 2012a, 2012b A E2 = 32π 5 αca 4 0 15λ 5 g S E2 = 1.11995 × 10 18 λ 5 g S E2 .…”
