摘要：

We have used photoelectron spectroscopy to observe thermal isomerization in cesium-halide cluster. anions. In many of the (CsX)(n)Cs-m(-) (X = Cl,Br,I; n = 2-7; m = 0, 1) systems we have studied, small changes' in the source nozzle temperature produce dramatic changes in the distribution of cluster isomers. When specific isomers are selectively photodepleted, isomer interconversion quickly reestablishes the thermal isomer distribution; even though the clusters are isolated in a cluster beam.
