Abstract
Multifragment decays of central collisions in Kr-84 + (197)AU at E/A = 35, 55, and 70 MeV are studied. The dependence of the extracted emiss ion time on the velocity of the fragment pair is investigated. More en ergetic pairs manifest a stronger Coulomb interaction, indicating emis sion from a source of smaller spatial-temporal extent than less energe tic pairs. This trend can be understood in the context of a statistica l model that allows the source characteristics to evolve as the fragme nts are emitted.
