Energy levels and radiative rates for inner shell transitions of Fe XVI
Abstract
Aims:In this paper we report calculations for energy levels and radiative rates for transitions in Fe xvi.
Methods: The General purpose Relativistic Atomic Structure Package (grasp) has been adopted for the calculations of energy levels and radiative rates.
Results: Energies for the lowest 134 levels among the (1s^22s^2) 2p^63ℓ, 2p^53s^2, 2p^53s3p, 2p^53s3d, 2p^53p3d, and 2p^53p2 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.
