We present first experimental evidence for intra-atomic double scattering of binary encounter electrons produced in collisions of 5.9 MeV/u U²⁹⁺ with neon, xenon, and molecular gases. A broad distribution of electrons is observed at a velocity twice the velocity of the moving ion ( v_P) at angles ϑ_e up to 135°. We attribute this emission pattern to well-known target binary encounter electrons around 2v_P at extreme forward laboratory angles that are subsequently elastically scattered in the target nuclear potential to the large angles observed.
