Rise and fall of multifragment emission
Physical Review Letters
(1991)
Abstract
We have studied multifragment decays of Au projectiles after collisions with C, Al, and Cu targets at a bombarding energy of 600 MeV nucleon. We find that with increasing violence of the collision, measured via the multiplicity of light particles, the mean multiplicity of intermediate-mass fragments originating from the projectile first increases to a maximum〈MIMF〉≃3 and then decreases again. Calculations using the Boltzmann-Uehling-Uhlenbeck model suggest that the fragmentation is governed by the energy Edep deposited into the projectile spectator and that〈MIMF〉reaches its maximum around Edep≃8 MeV/nucleon.
