Oscillator Strengths for Transitions in Ca XV and Fe XXI
Abstract
Energy levels and oscillator strengths (transition rates) have been calculated for the fine-structure transitions among the levels of the (1s2) 2s22p2, 2s2p3, 2p4, 2s22p3s, 2s22p3p, and 2s22p3d configurations of Ca XV and Fe XXI using the CIV3 and GRASP programs. The results are compared with the recently available theoretical values from the SuperStructure program. The differences among the various calculations are discussed, and the accuracy of the results is assessed.
