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 (Configuration Interaction version 3)
atomic structure code of Hibbert and the GRASP (General Relativistic
Atomic Structure Program) code of Dyall et al. (1989) 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.
