Abstract

The forward part of the new 4 pi detector Chimera has been recently installed at Laboratori Nazionali del Sud (LNS) in Catania. Beams of Sn-112 and Sn-124 at 35 MeV/nucl., useful for physics, were delivered on March 2000. Intermediate mass fragments (IMF) production and isospin effects in nuclear multifragmentation were investigated in reverse kinematics using Al-27, Ni-58,Ni-64 targets. A good on line isotopic identification of IMF and charged light particles (LCP) was obtained using DeltaE-E, DeltaE-Time of flight (TOF) and pulse shaping methods. Some preliminary results obtained on both elemental and isotopic distribution of light fragments show sizeable entrance channel isospin dependence.
