摘要：

Nuclei with Z up to 82 emitted in the Pb-208 + Au-197 reaction at E(lab) = 29 MeV per nucleon have been measured as a function of the associated neutron multiplicity. The data reveal the presence of strong correlations between character of a collision and neutron multiplicity. The trends suggest a disassembly of the nuclear system into a large number of nucleons and small fragments in the events with the highest neutron multiplicity. In such events, approximately one-third of the neutrons are released from the system and fragment yields decrease in an exponential fashion with increasing mass.
