Abstract
The emission of different secondary ions from inorganic (CsBr) and org anic (10(3) u peptide - valinomycin) targets is monitored as a functio n of the number of atoms of impacting Au(n)- cluster ions (n = 1 to 5) at constant energy of 100 keV. A method for determination of the mult iplicities (defined here as the number of ions of the same type emitte d per impact event) is described. The multiplicity is a measure of the ion emission probability in a single impact event and thus may provid e evidence for ''cooperative'' effects in polyatomic ion impact induce d sputtering.
