Phys. Rev. Lett. 50, 27–30 (1983)Time-of-Flight Measurements of Cesium-Iodide Cluster IonsReceived 30 July 1982; published in the issue dated 3 January 1983 Secondary ions [(CsI)nCs]+, with n up to ∼ 40, were produced by 8-keV Cs+ bombardment of CsI. The yield of clusters decreased smoothly with n when observed in a time-of-flight mass spectrometer at effective times ∼ 0.2 μs after emission. Clusters with n>7 were found to be metastable, with lifetimes ≪ 100 μs. A large anomaly in the population of the disintegration products was measured at ∼ 70 μs after emission, n=13 clusters being favored and n=14 and 15 suppressed. © 1982 The American Physical Society URL:
