Thermal photon-IMF anticorrelation: a signal of prompt multifragmentation?
R. Alba
Abstract
The mechanism responsible for IMF emission in central 58Ni + 197Au reactions at 30 and 45 MeV/nucleon is investigated by looking at the thermal bremsstrahlung photon production. An IMF - photon anticorrelation signal is observed, for central collisions, at 45 MeV/nucleon with IMF velocity around the center of mass value. This observation is proposed as an evidence for prompt nuclear fragmentation events.
