Abstract

Two variants of the free fall model for helium in the first autoionizational state have been proposed for calculating differential cross section for e – He (2s2) elastic scattering. At E = 7 eV impact energy the cross sections are evaluated numerically, making use of the classical trajectory method and are found sistematically higher for the case of the asynchronous atomic electrons motion than for the synchronous one.
