Light-Ion-Induced Multifragmentation: A Fast Evolutionary Process
GeV light-ion-induced reactions offer a unique tool for preparing hot, dilute nuclear matter. Mediated by multiple N-N scatterings and Δ-resonance excitations, central collisions produce a single, highly-excited source on a very fast time scale (20–30 fm/c). The subsequent evolution of such systems toward multifragment disassembly follows a much different trajectory in the nuclear temperature-density phase diagram than for heavy ions—where significant compression and longer time scales are typically involved. Thus, light-ion- and heavy-ion-induced reactions provide complementary perspectives on attempts to extend our knowledge of the nuclear equation-of-state to a much wider range of temperature and density.
