The Iron Project and the Rmax Project: Photoionization, Electron-Ion Recombination and Oscillator Strengths of Fe Ions, Fe~XVII and Fe~XXII

The Iron Project and the Rmax Project aim in detail study of radiative and collisional processes of astrophysically abundant atoms and ions, mainly iron and iron-peak elements, over a wide energy range, from infra-red to X-rays. The present work will report oscillator strengths for photo-excitations in Fe~XXII, photoionization cross sections and electron-ion recombination rates for Fe~XVII. The calculations were carried out in relativistic Breit-Pauli approximation. For Fe~XXII, allowed electric dipole, forbidden electric quadrupole, electric octupole, magnetic dipole and magnetic quadrupole transitions will be presented. They represent a set of 771 bound fine structure levels with 1/2 $\leq J \leq$ 17/2. The calculated energy levels were identified spectroscopically using quantum defect analysis. For Fe~XVII, results on photoionization and electron-ion recombination, total and level-specific obtained using the unified method, will be presented from the latest R-matrix calculations using a 60-level wave function expansion. The emphasis of this study is on the features in the high energy and high temperature region.
