Energy Levels, Oscillator Strengths and Forbidden Transition Probabilities in the Sc II Isoelectronic Sequence

Abstract

Empirical Slater parameters are derived from a study of energy levels in the isoelectronic sequence Sc II –Ni IX . Positions for some unobserved levels are predicted. Electric dipole oscillator strengths have been calculated for all possible transitions. Electric quadrupole and magnetic dipole transitions between and within the |$3^{{d}^{2}}$| and 3 d 4 s configurations are given.
