“…In the remaining m ≥ 2 progression, the neutral clusters exhibit a monotonic decrease with increasing size, i.e., number of indium atoms, which closely follows that observed for the pure indium clusters. This finding is in marked contrast with a similar experiment performed on silicon . In that case, the neutral Si m C, Si m C 2 , and Si m C 3 clusters showed pronounced yield maxima at m = 2, 1 and 2, respectively, which could be explained by the fact that these clusters exhibit the largest dissociation threshold (i.e., the lowest dissociation energy for loss of a Si atom).…”
