Abstract

Metastable decay of mercury/cesium complex cluster,HgnCs+, was measured by using a time-of-flight mass spectrometer of Osaka University. The TOF spectrometer is comprised of four electrostatic analyzers (ESAs). By scanning the applied voltage of the ESAs, MS/MS spectra and MS/MS/MS spectra can be obtained. The product-ion spectra generated from metastable decay of the complex cluster were obtained by MS/MS analysis. The product ions of the decay were determined as Cs+andHgnCs+. Sequential decays were also observed with the MS/MS/MS analysis mode of the spectrometer. The position occurring metastable decay producing detected ion can be selected with the TOF spectrometer. To compare the product-ion yield generated at two different positions, the rate constant of the decay can be estimated. In preliminary experiments using glycerin-trimer ion, [3g+H]+, as a precursor, the obtained rate constant of the decay is 2.0×104l/s.
