Abstract

Multinucleon transfer in Kr86+Ni64 at an incident energy of 25 MeV/nucleon is for the first time investigated with a microscopic dynamics model: improved quantum molecular dynamics (ImQMD) model. The measured isotope distributions are reasonably well reproduced by using the ImQMD model together with a statistical code (gemini) for describing the secondary decay of fragments. The reaction mechanism is explored with the microscopic dynamics simulations from central to peripheral collisions. In central collisions there exists a strong competition among fusion, deep-inelastic scattering, and multifragmentation at such an incident energy. In semiperipheral collisions, binary scattering together with nucleon transfer is dominant, and the probability of elastic + inelastic scattering events increases rapidly with impact parameter in peripheral collisions and approaches one when b>14 fm. The mass-total kinetic energy distribution in central collisions due to the competition is quite different from those in peripheral collisions and the distribution of total kinetic energy loss for binary events with nucleon transfer is much more broader than those without transfer.
