Abstract
Experimental evidence for intra-atomic double scattering of fast Binary Enc ounter (BE) electrons produced in collisions of 5.9 MeV/u U29+ with various gas targets is presented. A broad distribution of electrons displaying the shape of the (BE) peak at twice of the velocity of the ion beam at angles up to 135 degrees is observed in the double differential electron emission spectra, This emission is attributed to target electrons ejected in a knock -on collision that are subsequently elastically scattered at their own targ et nuclear potential.
