J/A+A/466/763 Electron-impact excitation of Fe^19+^ (Witthoeft+, 2007) ================================================================================ Atomic Data from the IRON Project. LXIII. Electron-impact excitation of Fe19+ up to n=4. Witthoeft M.C., Del Zanna G., Badnell N.R. =2007A&A...466..763W ================================================================================ ADC_Keywords: Atomic physics Keywords: Energy levels, F-like Fe 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. 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.
