摘要：

The Breit-Pauli R-matrix codes are utilized in a detailed study of the photoionization of the ground state of Fe XVI (2s(2)2p(6)3s(2)S(1/2)). High resolution total and partial cross sections an obtained using 37 J pi configuration interaction type wavefunctions to represent the residual ion, Fe XVII, after 3s, 2p and 3s photoionization. For the total cross section, the work of Verner et al, and previous Opacity Project calculations are in fair agreement with the present results, while relativistic effects are seen to have a noticeable but not an overly significant effect on the background cross section. The derived partial cross sections are used in a calculation of rates for the recombination of states of Fe SW to the ground state of Fe XVI.
