Multiconfiguration Hartree-Fock autoionization calculations near the 3p excitation edge of the transition metals

We report electron-impact excitation relative scattering cross sections for the transition metals $^{21}$SC through $^{27}$Ni near the 3p excitation edge.\footnote{K. Nuroh, Phys. Rev. B\textbf{ 77}, 125137 (2008)} The first set of calculations is based on the theoretical model of random-phase approximation for core-electron scattering in solids in which only electrostatic interactions are taken into account.\footnote{K. Nuroh, Phys. Rev. B \textbf{70}, 205115 (2004)} The second set of calculations is based on an analysis that hinges on the Bethe-Born approximation\footnote{K. Nuroh, J. Phys. C \textbf{20}, 5305 (1987)} in which both electrostatic and magnetic interactions are incorporated. Both sets of calculations show trends in Z that are manifested in available measurements.
