Multifragmentation with Indra@GSI: From the Fermi to the   Participant-Spectator Domain
  With INDRA at GSI, multifragmentation was studied in 197Au + 197Au reactions at bombarding energies 40 to 150 MeV per nucleon. The mechanisms of fragment production at mid-rapidity in peripheral collisions and the interplay of collective motion and fragmentation in central collisions were investigated. The balance energy for squeeze-out, i.e. the transition energy from in-plane to out-of-plane enhancement of the particle and fragment emissions is determined as a function of the impact parameter.
