Oscillator Strengths and Radiative Rates for Transitions in Fe XV
Abstract
We report oscillator strengths and radiative decay rates for 1108 optically allowed and intercombination transitions among the lowest 87 fine-structure energy levels of Fe XV. Two independent calculations are carried out using the CIV3 atomic structure code of Hibbert and the GRASP code of Dyall et al. The results from the two calculations agree well for almost all the strong transitions. However, there are notable disagreements between the two calculations for a few relatively weaker transitions involving some levels belonging to the 3p4d and 3p4f configurations. These differences, along with those of other available calculations, are discussed, and the accuracy of the data is assessed.
