Description
The CHIFAR experiment at the INFN-LNS coupled the 4$\pi$ CHIMERA multi-detector with 10 telescopes of the FARCOS (Femtoscope Array for COrrelations and Spectroscopy) correlator. FARCOS is a triple-stage telescope consisting of two DSSSDs (Double Sided Silicon Strip Detectors, 300 and 1500 $\mu$m thick) and 4 CsI(Tl) scintillators (6 cm thick), featuring high energy and angular resolution. Charged particles were identified ($\Delta$E - E method) and their impinging positions were reconstructed (Pixelation technique), in the laboratory frame.
The current analysis utilizes the merged data from the CHIMERA-FARCOS coupling to investigate the influence of the isospin contribution on the dynamical emission in Heavy Ion collisions at an incident beam energy of 20 AMeV. The projectiles - $^{124}$Sn, $^{112}$Sn, $^{124}$Xe – and the targets -$^{64}$Ni, $^{58}$Ni, $^{64}$Zn – were specifically selected to emphasize the isospin content. Preliminary findings regarding the isospin distribution will be presented: the role of the N/Z ratio in the emission mechanisms of the nuclear reactions is highlighted through more stringent constraints on CHIMERA global variables (e.g. total kinetic energy, total multiplicity of charged particles, reaction plane).
