Photoionization Modeling and the K Lines of Iron
- T. Kallman, P. Palmeri, M. Bautista, C. Mendoza, J. Krolik
- Physics, Geology
- 11 May 2004
We calculate the efficiency of iron K line emission and iron K absorption in photoionized models using a new set of atomic data. These data are more comprehensive than those previously applied to the…
Modeling of Iron K Lines: Radiative and Auger Decay Data for Fe II-Fe IX
- P. Palmeri, C. Mendoza, T. Kallman, M. Bautista, M. Meléndez
- Physics
- 16 June 2003
A detailed analysis of the radiative and Auger de-excitation channels of K-shell vacancy states in Fe ii-Fe ix has been carried out. Level energies, wavelengths, A-values, Auger rates and…
