Description
Neutron multiplicity measurements have been performed for reactions induced by a 29 MeV/u 208Pb beam on a 197Au target. These neutron multiplicities have been measured in a 4π Gd loaded liquid scintillator neutron detector in coincidence with charged products as well as in single mode. The distribution of events observed through solid-state detectors depends very strongly on the associated neutron multiplicity. Besides the elastic and quasi-elastic events associated to the lowest neutron multiplicity values, binary fission has been only identified for rather peripheral collisions with rather low excitation energies. For the most central collisions the system disassembles in a large number of light fragments, and the number of emitted neutrons exhaust almost totally the total neutron excess of the system (N-Z).
