Time-of-flight measurements of cesium-iodide cluster ions

Journal Article · · Phys. Rev. Lett.; (United States)
Secondary ions ((CsI)/sub n/Cs)/sup +/, with n up to approx.40, were produced by 8-keV Cs/sup +/ bombardment of CsI. The yield of clusters decreased smoothly with n when observed in a time-of-flight mass spectrometer at effective times approx.0.2 ..mu..s after emission. Clusters with n>7 were found to be metastable, with lifetimes <<100 ..mu..s. A large anomaly in the population of the disintegration products was measured at approx.70 ..mu..s after emission, n = 13 clusters being favored and n = 14 and 15 suppressed. .ID LV2149
