Dynamical emission of heavy fragments in the 112,124Sn+58,64Ni reactions at 35 AMeV as seen with CHIMERA

A quantitative comparison regarding absolute cross sections associated to Statistical and Dynamical Fission in the system 124Sn+64Ni and112Sn+58Ni experimentally investigated at 35 AMeV beam energy is presented. It results that Dynamical Fission process is about two times more probable in the neutron rich 124Sn+64Ni system than in the 112Sn+58Ni neutron poor one. At this point of our analysis it is not clear if the observed difference is originated by different entrance channel Isospin (N/Z) content or by different size between the two investigated systems

Investigation of the isospin dependences in Sn+ni and Sn+Al systems

The ISOSPIN was the first experiment that uses 4\ucf CHIMERA multi-detector, mounted in its complete configuration at the LNS in Catania/Italy. The aim of the project is to explore the isospin properties of the Nuclear Matter Equation of State (NMEOS) by studying heavy ion collisions at intermediate energies. The analysis of the following reactions is in progress: 124Sn+27Al,124Sn+58Ni,124Sn+64Ni at 25 MeV/A and 35 MeV/A. The results of light charged particles identification, CsI(Tl) detectors energy calibration and preliminary physical results will be presented
