In the spring 2009, an experimental campaign has been performed by the Nuclex-Hector collaboration at the Laboratori Nazionali di Legnaro in order to study different reaction channels by detecting, in coincidence, Evaporation Residue (ER), Charged Particles and Fragments and high energy gamma rays from Giant Dipole Resonance (GDR). The studied system was 48Ti+40Ca at 600, 450 and 300 MeV using a composite apparatus formed by 48 triple-phoswich detectors for ER and other ejectiles at the forward angles (about 6-13 deg), the GARFIELD ΔE-E forward drift chamber for the charged particles between 30 and 85° and the HECTOR apparatus at the backward angles for γ-rays.

The aim of the campaign was the study of the GDR as a function of the excitation energy of the Compound Nucleus (CN) and of its spin. For a rather precise evaluation of these quantities, it is important to measure the amount of charge, mass and energy removed from the nuclear system by pre-equilibrium particles and to select the different decay channels (fission and/or alpha chain) in order to disentangle the different angular momentum associated to the CN.

Some preliminary results about Light Charged Particles and Fission Fragment mainly from the 600 MeV reaction will be shown in the talk.
