摘要

By using the semi-relativistic distorted-wave Born exchange method, electron impact cross sections for the Fe23+ line emission 3d(5/2) --> 2p(3/2) are calculated. The calculation involves line formation by direct electron-impact excitation, radiative cascade, resonant excitation, and dielectronic recombination satellites with captured electron in the n greater than or equal to 5 levels. The results shaw a good agreement with the recent measurements.
