摘要：

Products of Pb-208+Ni-64 collisions at an energy 12% above the Coulomb barrier have been studied in a gamma spectroscopy thick target experiment. The product yield distribution has been established from the gamma-gamma coincidence analysis supplemented by target radioactivity measurements. Neutron evaporation from excited primary products has been estimated to determine the pre-emission map of fragments. We discuss the transfer of protons and neutrons between the colliding ions in terms of the N/Z ratio equilibration. (C) 2003 Elsevier B.V. All rights reserved.
