Abstract
Multifragment breakup of and nuclei bombarded by ions has been studied with the Indiana Silicon Sphere detector array. To investigate the properties of the emitting source as a function of excitation energy, a two-component moving-source analysis has been performed on the intermediate-mass-fragment spectra, gating on excitation energy. The results provide evidence for nuclear expansion∕dilution to a value of prior to breakup. For the most violent events, relatively low source velocities of and slope temperatures of are obtained for the dominant thermal-like source. The dependence of isotope ratios on deposition energy and ejectile kinetic energy is examined for H and He isotopes, and the caloric curves for the data are presented.
