Abstract
The bombardment of metal halides (MX) by keV — primary particles causes the emission of secondary atomic (M+, X-) and cluster [(MX)nM+; (MX)nX-; n = 1,2,...) ions. Once the secondary cluster ions leave the primary interaction region, they can undergo metastable decays due to the vibrational energy stored in the cluster bond during the initial production process. A large fraction of secondary cluster ions from metal halides, as well as molecular ions from organic materials, has indeed been observed to be metastable. We have studied the metastable decays of some CsI clusters and determined the corresponding rate constants.
