| Abstract | Abstract. This paper reports the first close-coupling photoionisation calculation of Fe XVII, and provides accurate total and partial cross sections for photon energies up to 450 Ryd. The total and first partial photoionisation cross sections, the latter obtained when the Fe XVIII ion is left in the 2s 2 2p 52 P o ground state, are dominated by resonance structure for photon energies in the range from threshold to excitation of the first excited state (2s2p 62 S) of Fe XVIII. This is the first time that such structure has been determined. The background cross section is found to be in good agreement (to within 10%) with the results of Verner and co-workers for the total cross section, and for the partial cross sections corresponding to 2p and 2s photoejection, respectively.
