Abstract

Metal-rich K_{1 - 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 Na_{1 - 9} (NaF)_n⁺ and Cs_{1 - 5} (CsI)_n⁺ clusters. It is interesting to note that K_{2, 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.
