Abstract:
Transitions between the five fine-structure levels in the 3s 23p 3 ground configuration of Fe XII (P-like) are of interest in astrophysics and terrestrial plasma diagnostics. The decay rates give rise to level lifetimes in the millisecond range, which have been measured recently at a heavy-ion storage ring. While most of the 3s 23p 23d levels are short-lived, two of these levels have no E1 decay channels and may also have millisecond lifetimes. We present HFR and MCDF calculations of the E1, M1, E2 and M2 transition rates between the 3s 23p 3, 3s3p4 and 3s 23p 23d levels and compare the lifetime results to most recent experimental data as well as to other predictions.
