We have determined the relative mass peak intensities of clusters formed from the sputtering of isotopically enriched silver foil in the presence and absence of CH3I vapor. The important results can be summarized as follows 1 the relative intensity of the AgX mass peaks showed a steady decrease with increasing X due to the drop in their formation probability with oscillations the correlate well with the previously published electron affinities of the corresponding Agx neutral clusters which is in agreement with the jellium model predictions and thus reflects the relative stability of the AgX clusters 2 An oscillatory correlation and the shell closing effect for eight delocalized electrons is found between the measured electron affinities EA for AgX and mass peak intensities of the clusters AgX 1I- and not with the AgXI- mass peak intensities.
