The charge-state distributions of ions emerging from carbon foils were compared for equal velocity monoatomic negative ions incident on the foil. Such comparisons were performed for O/sub 2//sup -/ vs O/sup -/ and for C/sub 3//sup -/ vs C/sup -/ and C/sub 4//sup -/ vs C/sup -/. Measured charge state distributions are shown for carbon and oxygen respectively and how the observed effect varies with foil thickness for the oxygen case. In all cases, the distribution is shifted toward lower average charge states for the molecular beams and the effect persists even though attenuated up to and including the thickest foils used. The most straightforward interpretation of these results is that for each component of the cluster there are more correlated electrons available for pickup than for single ions. 1 reference. (JFP)
