Description

58Ni+58Ni collisions at 32 MeV/nucleon have been studied with the 4π multidetector INDRA. The evolution from binary (dissipative) collisions to a fusionlike process is evidenced with decreasing impact parameter throughout a set of experimental observables within a discriminant analysis. Preequilibrium effects and characteristics of a single-source emission are discussed. A coexistence (bimodality) between two decay mechanisms is pointed out and examined in the context of a multiple-fragment (particle) emission
