Abstract:
In this paper we report calculations for energy levels and radiative
rates for transitions in Fe XVI. The General purpose Relativistic
Atomic Structure Package GRASP has been adopted for the calculations
of energy levels and radiative rates.
Energies for the lowest 134 levels among the (1s22s2) 2p63l,
2p53s2, 2p53s3p, 2p53s3d, 2p53p3d, and 2p53p2
configurations of Fe XVI are reported. Additionally, radiative rates,
oscillator strengths, and line strengths are reported for all electric
dipole (E1), magnetic dipole (M1), electric quadrupole (E2), magnetic
quadrupole (M2), and electric octupole (E3) transitions among these
levels. Comparisons are made with the available results in the
literature, and the accuracy of the present results is assessed.
Finally, lifetimes for all excited levels are also listed, although no
measurements are presently available with which to compare these.
