Summary
In Heavy Ion Collisions (HIC) at Fermi energy (10 MeV/nucleon ≤ E/A ≤ 100 MeV/nucleon) the produced hot nuclear systems decay by different mechanisms with characteristic time scales (neck emission, dynamical and sequential fission, multifragmentation, fusion-evaporation, ecc.), depending on the available energy, sizes, isospin of the interacting projectile and target systems.
The space-time sensitivity of different fragment-fragment correlation functions of Intermediate Mass Fragments (IMFs) of atomic charges in the range 3≤ Z ≤ 25 have been investigated in order to pin down the phase space characteristic of their emission region.
In particular, IMF-IMF correlation functions have been measured for the systems 112,124Sn+58,64Ni investigated with the forward part of CHIMERA at the bombarding energy of E/A= 35 MeV/nucleons where a strong competition between dynamical and statistical production mechanism of heavy fragments has been found [1]. Comparisons of the data with theoretical simulations will be also presented.
