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 2s2 2p3, 2s 2p4, 2p5,
2s2 2p2 3l, and 2s 2p3 3l configurations while the second
calculation also includes the levels from the 2s2 2p2 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.
Description:
An extension of Table 2 in the paper, this data file contains a full
listing of the energy levels from the n=4 calculations described in
the text. The energy-ordered index, energy in Ry, configuration index,
2J, and parity are listed in the file.
