Research Abstract

The lifetimes for metastable states of the chain carbon and hydrocarbon anions from dimers to hexamers were measured by using an electrostatic storage ring equipped at TMU. All the kinds of the hydrocarbon anion have a few metastable states with a lifetime in the millisecond range from decay plot analysis. Vis/near-IR excitation spectra of the hydrocarbon tetramer anions were measured by detecting neutral species produced by photoabsorption. The yield dependence of the laser wave length and the storage time in the ring were observed.
