Calculations of the Atomic Structure for Fe XVII Lines

Energy levels, line strengths, oscillator strengths, radiative decay rates and fine structure collision strengths are presented for sixteen-times ionized iron (Fe XVII). The atomic data are calculated with the AUTOSTRUCTURE code, where relativistic corrections are introduced according to the Breit–Pauli distorted wave approach. The calculations of atomic data for 89 fine-structure levels generated from eleven configurations 2s2p, 2s2p (3s, 3p, 3d), 2s2p (4s, 4p, 4d, 4f) and 2s2p (3s, 3p, 3d) of the Ne-like Fe ion are presented. Fine structure collision strengths for transitions from the ground and the first four excited levels are presented at four electron energies: 75, 125, 175, and 250 Ry. These atomic structure data are compared with the available experimental and theoretical results.
