Abstract
A numerical method has been developed to obtain the kinetic energy release distribution from a mass‐analysed ion kinetic energy peak profile for a metastable ion decomposition occurring in a collision cell floated at high voltage. The method has been applied to the unimolecular dissociation of the tert‐butylbenzene molecular ion. The kinetic energy release distribution thus obtained was nearly invariant to the applied voltage. Peak tailing due to dissociation in the field region could be reproduced adequately The method may be useful for the investigation of unimolecular ion decomposition in narrow time‐ and energy‐windows.Keywords
