Size distributions of fragments from multiply charged clusters have been determined. On a time scale of 0.1 ms with respect to ionization, triply charged CO/sub 2/ clusters of size nroughly-equal114 are found to fission extremely asymmetrically, their doubly charged fragments carrying 92% of the mass. For doubly charged CO/sub 2/ clusters, however, evaporation of neutral monomers is the only channel for delayed dissociation. A model, based on the liquid-drop approximation, can quantitatively account for the lower size limits of multiply charged clusters as well as for the distribution of fission fragments from (CO/sub 2/)/sub roughly-equal114/ /sup 3 +/. .AE
