摘要:

Yields and energy spectra of neutral and charged particles sputtered from Cu target under 5.5 keV Ar+ion bombardment have been measured. The yield of Cunneutrals falls off rapidly with increasingnthat can be explained by the recombination model. The yield of Cun+ions depends unmonotonously onn.The ionization probability of sputtered particles is described by an exponential dependence exp[-(In- ϕ)/ε0], whereInis the ionization potential of Cuncluster, ϕ is the work function and ε0is a parameter.
