Abstract
Electron emission number statistics have been measured for 8 keV H+ ions in collisions with clean polycrystalline copper at 80 degrees and 67 degrees. Also, in a new development, electron number statistics have been recorded for reflected particles using coincidences between the reflected particles and the emitted electrons. The results of both coincidence and non-coincide nce measurements fitted Polya distributions, with a higher mean emission va lue in the coincidence case. A model has been developed to interpret the di fference between the coincidence and non-coincidence electron number statis tics.
