Abstract：
Multifragmentation is studied in correlation with energetic protons.A cold multifragmentation pattern is proposed based on the numerical simulation of the stochastic Boltzmann-Langevin model for describing the intermediate heavy ion collisions,i.e.,a sizable fraction of the available energy is released from the system by fast non-equilibrium proton emission,in which the explosion is caused to happen by a violent,but cold expansion of the system.Some typical examples simulated for ⁴⁰Ca+⁴⁰Ca central collisions at 90MeV/u are presented.A possible experimental signature which could be detected with the help of a 4π detector system is suggested.
