Abstract:
Symmetric ( [iopmath latex="$\rm e, 2e$"] e,2e [/iopmath] ) differential cross section measurements for argon at an incident energy of 64.6 eV are presented from the coplanar to the perpendicular plane geometry. The outgoing electrons were detected at symmetric scattering angles and with the same energy. These measurements are compared with analogous results at the same incident energy using helium as the target. The argon ( [iopmath latex="$\rm e, 2e$"] e,2e [/iopmath] ) cross section shows a rich and complex structure as the scattering geometry changes, while the very deep interference minimum found in helium is missing.
