Abstract

We present measurements of the relative electron-impact-excitation cross sections for the 1 $s^{2}$ ${}^{1}S_{0}$ –1s2p ${}^{1}P_{1}$ , 1 $s^{2}$ ${}^{1}S_{0}$ –1s2p ${}^{3}P_{2}$ , 1 $s^{2}$ ${}^{1}S_{0}$ –1s2p ${}^{3}P_{1}$ , and ${1 s}^{2}$ ${}^{1}S_{0}$ –1s2s ${}^{3}S_{1}$ transitions for the He-like ion, ${Fe}^{24 +}$ . The measurements were made at two electron energies: 6.86 and 9.94 keV. The cross-section measurements are compared with theoretical calculations.
