R-Matrix calculations for opacities: IV. Convergence, completeness, and comparison of relativistic R-matrix and distorted wave calculations for FeXVII and FeXVIII
L. Zhao, S. N. Nahar, W. Eissner +1
To investigate the completeness of coupled channel (CC) Breit-Pauli R-Matrix (BPRM) calculations for opacities, we employ the relativistic distorted wave (RDW) method to complement…
Atomic data from the Iron Project.LVIII. New radiative transition probabilities for Fe IV including fine structure
Sultana N. Nahar, Anil K. Pradhan
We present new calculations for transition probabilities of Fe IV, with much more extensive datasets than heretofore available. The large-scale close coupling R-matrix calculations…
The 6.7 keV KALPHA complex of He-like iron in transient plasmas
Justin Oelgoetz, Anil K. Pradhan
Time dependent numerical simulations of the K ALPHA complex of Fe XXV are carried out as a function of temperature/density/radiation field variations in high-temperature astrophysi…
Theoretical FeI/II/III Emission-Line Strengths from Active Galactic Nuclei with Broad-Line Regions
T. A. A. Sigut, Anil K. Pradhan, Sultana N. Nahar
We present theoretical iron emission line strengths for physical conditions typical of Active Galactic Nuclei with Broad-Line Regions. The non-local thermodynamic equilibrium (NLTE…
Atomic data from the Iron Project. LIII. Relativistic allowed and forbidden transition probabilities for Fe XVII
Sultana N. Nahar, Werner Eissner, Guo-Xin Chen +1
An extensive set of fine structure levels and corresponding transition probabilities for allowed and forbidden transitions in Fe XVII is presented. A total of 490 bound energy leve…
