Excitation-Ionization of Helium to He⁺ (n = 2) at 365.8 eV
Abstract
A second Born calculation of the (e, 2e) triple differential cross section for excitation-ionization of helium to He+(n = 2) in coplanar asymmetric geometry is found to be in excellent agreement with recent (relative) measurements of Rouvellou et al. The second Born cross section is very much larger, by about a factor of four, than the corresponding first Born cross section, a trend that is consistent with absolute total cross section measurements for ionization to He+ (2p) at the same impact energy.
