Abstract

Ar+Ni reactions have been studied to fix some constraints on the isospin dependence of the level density. The coupling of INDRA and VAMOS apparatuses allows to obtain highly exclusive data . The preliminary results on the Ar+Ni fusion-evaporation cross sections suggest a dependence on the entrance channel mass asymmetry.
