Formation and decay of hot nuclei in heavy ion collisions

Abstract : The properties of the multifragmentation of ``hot sources'' produced in the 40Ca +40Ca reaction have been studied at a beam energy 35 MeV/nucleon. Two signatures of prompt multifragmentation, which make use of special features of particle emission from the ``freeze out volume'', together with an analysis of the reduced relative velocity between pairs of intermediate mass fragments, indicate the presence of a transition from sequential decay to prompt multifragmentation at an excitation energy of about 3 MeV/nucleon.
