    Electric dipole transition probabilities, oscillator strengths, and lifetimes for Co16+
    (CANADIAN SCIENCE PUBLISHING, NRC RESEARCH PRESS, 2016) Celik, G.; Ates, S.; Tekeli, G.
    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.

    Oscillator strengths for singly ionized oxygen
    (SPRINGER, 2009) Ates, S.; Tekeli, G.; Celik, G.; Akin, E.; Taser, M.
    The electric dipole oscillator strengths for multiplet and individual lines between some doublet and quartet levels have been calculated using the weakest bound electron potential model theory (WBEPMT) in singly ionized oxygen. We employed both numerical Coulomb approximation (NCA) wave functions and numerical non-relativistic Hartree-Fock (NRHF) wave functions for expectation values of radii in determination of parameters. The calculated oscillator strengths have been compared with available theoretical and experimental results. A good agreement with results in literature has been obtained. Moreover, oscillator strengths not existing in the literature for some highly excited levels have been obtained using this method.

    Oscillator Strengths of Allowed Transitions for O III
    (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2012) Ateş, Ş.; Çelik, G.; Tekeli, G.; Taşer, M.
    The electric dipole oscillator strengths for lines in O III between some singlet and triplet levels have been calculated using the weakest bound electron potential model theory and the quantum defect orbital theory. In the calculations, both multiplet and fine-structure transitions are studied. The calculated oscillator strengths have been compared with available theoretical and experimental results. Good agreement with results in the literature has been obtained.
