cds-question@unistra.fratomic-physicsAn 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 levels of Fe XVII of total angular momenta 0<=J<=7 of even and odd parities with 2<=n<=10, 0<=l<=8, 0<=L<=8, and singlet and triplet multiplicities, are obtained. They translate to over 2.6x10^4^ allowed (E1) transitions that are of dipole and intercombination type, and 2312 forbidden transitions that include electric quadrupole (E2), magnetic dipole (M1), electric octopole (E3), and magnetic quadrupole (M2) type representing the most detailed calculations to date for the ion. Oscillator strengths f, line strengths S, and coefficients A of spontaneous emission for the E1 type transitions are obtained in the relativistic Breit-Pauli R-matrix approximation. A-values for the forbidden transitions are obtained from atomic structure calculations using codes SUPERSTRUCTURE and GRASP. The energy levels are identified in spectroscopic notation with the help of a newly developed level identification algorithm. Nearly all 52 spectroscopically observed levels have been identified, their binding energies agreeing within 1% with our calculation. Computed transition probabilities are compared with other calculations and measurement. The effect of 2-body magnetic terms and other interactions is discussed. The present data set enhances by more than an order of magnitude the heretofore available data for transition probabilities of Fe XVII. Erratum: A bug was detected and corrected in early 2007 in one of the stages called RECUPD (Storey, Berrington, Werner 2007, private Iron Project communications) of the Breit-Pauli R-matrix (BPRM) codes of the Iron Project. It was related to the the phase factor of dipole matrix elements of the Iron Project (Berrington et al., 1995, Comput. Phys. Commun. 92, 290) and affected certain transition probabilities. The calculations for ions have been repeated for corrected results in order to replace the earlier results.
