Production mechanism of new neutron-rich heavy nuclei in the reaction
Abstract
Here, the multinucleon transfer reaction of 136Xe + 198Pt at Elab = 7.98MeV / nucleon is investigated by using the improved quantum molecular dynamics model. The quasielastic, deep-inelastic, and quasifission collision mechanisms are studied via analyzing the angular distributions of fragments and the energy dissipation processes during the collisions. The measured isotope production cross sections of projectile-like fragments are reasonably well reproduced by the calculation of the ImQMD model together with the GEMINI code. The isotope production cross sections for the target-like fragments and double differential cross sections of 199Pt, 203Pt, and 208Pt are calculated. It is shown that about 50 new neutron-rich heavy nuclei can be produced via deep-inelastic collision mechanism, where the production cross sections are from to 10–3 to 10–6 mb. The corresponding emission angle and the kinetic energy for these new neutron-rich nuclei locate at 40°–60° and 100–200 MeV, respectively.
