Abstract

We present results for the electron-impact excitation of N-like Fe as part of the RmaX network. R-matrix theory using an intermediate-coupling frame transformation method is used to obtain level-resolved collision strengths. Separate calculations are performed using different target expansions. The first is a 215 level close-coupling calculation which has the 2s^2^ 2p^3^, 2s 2p^4^, 2p^5^, 2s^2^ 2p^2^ 3l, and 2s 2p^3^ 3l configurations while the second calculation also includes the levels from the 2s^2^ 2p^2^ 4l configurations for a total of 302 close-coupling levels. The effect of the additional resonant enhancement of the larger calculation is explored and compared with a previous IRON Project report and other, more recent, calculations. As a final comparison, we model an astrophysical plasma using the results of the present calculations and previous work.
