2D DCSs for elastic scattering of electrons with the full potential of Ar+ at large scattering angles of 110°–180°. The incident electron momenta are (a) 0.45–0.75, (b) 0.60–1.00, (c) 0.75–1.20, and (d) 1.00–1.60, corresponding to the high-energy plateau regions for the peak intensities of 0.6×1014 W/cm2, 1.1×1014 W/cm2, 1.7×1014 W/cm2, and 2.9×1014 W/cm2, respectively.
