Abstract

We show new data from the $^{64}$Ni+$^{124}$Sn and $^{58}$Ni+$^{112}$Snreactions studied in direct kinematics with the CHIMERA detector at INFN-LNSand compared with the reverse kinematics reactions at the same incident beamenergy (35 A MeV). Analyzing the data with the method of relative velocitycorrelations, fragments coming from statistical decay of an excitedprojectile-like (PLF) or target-like (TLF) fragments are discriminated from theones coming from dynamical emission in the early stages of the reaction. Bycomparing data of the reverse kinematics experiment with a stochastic meanfield (SMF) + GEMINI calculations our results show that observables from neckfragmentation mechanism add valuable constraints on the density dependence ofsymmetry energy. An indication is found for a moderately stiff symmetry energypotential term of EOS.
