The forward part of the new 4π detector Chimera has been recently installed at Laboratori Nazionali del Sud (LNS) in Catania. Beams of 112Sn and 124Sn 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 27Al, 58,64Ni targets. A good on line isotopic identification of IMF and charged light particles (LCP) was obtained using ΔE-E, ΔE-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.

Abstract
The forward part of the new 4π detector Chimera has been recently installed at Laboratori Nazionali del Sud (LNS) in Catania. Beams of 112Sn and 124Sn 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 27Al, 58,64Ni targets. A good on line isotopic identification of IMF and charged light particles (LCP) was obtained using ΔE-E, ΔE-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.Pubblicazioni consigliate
