Abstract

Metal-rich K1 - 5 (KI)n+ (n ∼27) clusters were produced by the supersonic cooling expansion of laser-induced KI plasma. The obtained mass spectroscopic peaks show the unique magic numbers at n = 9, 13, and 22 for K1(KI)n; n = 8, 12, and 21 for K2(KI)n; n = 8, 12, 16, and 21 for K3(KI)n; n = 7, 9, 11, and 13 for K4(KI)n; and n = 12 and 21 for K5(KI)n. These magic numbers are fairly different from those of other reported metal-rich Na1 - 9 (NaF)n+ and Cs1 - 5 (CsI)n+ clusters. It is interesting to note that K2, 3, 5 (KI)n+ clusters have the same magic numbers at n = 12 and 21 and possess structures that are closely related to the 3 × 3 × 3 and 3 × 3 × 5 cubic structures with the excess electron at the side anion vacancy or the center anion vacancy.
