Abstract:

 Dissociation studies of mass-selected cluster ions have been carried out on a home-made apparatus. From analysis of the recorded dissociation mass spectra, it was found that fragmant distribution of dissociated cluster ions follows a statistical distribution model. In this paper, kinetic equations of two dissociation pathways are discussed and their analytical solutions are presented. Based on the distribution functions, recorded dissociation mass spectra of cluster ions are analyzed and attributed to the different fragmentation channels.
