Abstract
Photoelectron spectra obtained from (CsXCs- (X=Cl,Br,I) cluster anions are strongly dependent on the temperature of the laser vaporization s ource in which they were produced. Spectral features that were present in clusters emerging fr om the source at room temperature disappear w hen the source is cooled to low temperature. This effect is consistent with spontaneous thermal isomerization in the isolated clusters, a pr ecursor to the melting transition ia bulk materials.
