The stability of ( 02); ions produced by electron attachment to a neutral cluster beam has been studied with a double-focusing sector field mass spectrometer. Besides monomer evaporation via metastable dissociation reactions (Oz);\*-(Oi);?, t O2 it was possible to observe for the fint time metastabl

✦ Synopsis
Unimolecular dissociation of metastable excited states of (O,),,-* into (02);-l cluster anions has been detected and studied quantitatively for n in the range of 13 to 22. The apparent metastable (decay rates determinedincrease with cluster size in from -5000 s-l (for n = 13) up to-8 5 0 0 ~-~ for n = 22).

## Abstract We report on the gas phase reactions of small Fe^+^~__n__~ clusters (__n__ = 2–10) with O~2~, N~2~O and CO~2~ in an FT‐ICR mass spectrometer. Under our experimental conditions, clusters of all sizes reacted readily with O~2~ and all but the dimer reacted with N~2~O. Only the smallest Fe
