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.
