Secondary electron emission from Au by medium energy atomic and molecular ions

Number distributions of secondary electrons emitted from a Au metal surface have been
measured for atomic and molecular ions of H+, He+, C+, N+, O+, H+ 2, H+ 3, HeH+, CO+
and O+ 2 in the energy range 0.3–2.0 MeV. The emission statistics obtained are described
fairly well by a Pólya function. The Pólya parameter b, determining the distribution shape, is
found to decrease monotonously with increasing emission yield γ, revealing a surprising
relationship of bγ∼ 1 over the different projectile species and impact energies. This finding …
