Elastic large-angle scattering of electrons by multiply charged ions

Abstract

Differential cross sections for the elastic scattering of electrons by multiply charged ions have been measured at scattering angles between 32 and 148 .Mainly at backward angles the cross section deviates remarkably from the Rutherford cross section showing oscillations due to the structure of the ionic core.Experimental results obtained for Ar 8+ ions and different Xe q+ ions (3 q 6) are found to compare well with theoretical calculations.
