Abstract
We present first experimental evidence for intra-atomic double scatter ing of binary encounter electrons produced in collisions of 5.9 MeV/u U29+ with neon, xenon, and molecular gases. A broad distribution of el ectrons is observed at a velocity twice the velocity of the moving ion (nu p) at angles theta(e) up to 135 degrees. We attribute this emissi on pattern to well-known target binary encounter electrons around 2 nu p at extreme forward laboratory angles that are subsequently elastica lly scattered in the target nuclear potential to the large angles obse rved.
