Abstract We have used photoelectron spectroscopy to observe thermal isomerization in cesium-halide cluster anions. In many of the (Cs{ital X}){sub {ital n}}Cs{sub {ital m}}{sup {minus}} ({ital X}=Cl,Br,I; {ital n}=27; {ital 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. {copyright} {ital 1996 The American Physical Society.}
