Background: Multinucleon transfer reactions (MNT) are a competitive tool to populate exotic neutron-rich nuclei in a wide region of nuclei, where other production methods have severe limitations or cannot be used at all. Purpose: Experimental information on the yields of MNT reactions in comparison with theoretical calculations are necessary to make predictions for the production of neutron-rich heavy nuclei. It is crucial to determine the fraction of MNT reaction products which are surviving neutron emission or fission at the high excitation energy after the nucleon exchange. Method: Multinucleon transfer reactions in 136 Xe + 238 U have been measured in a high-resolution γ -ray/particle coincidence experiment. The large solid-angle magnetic spectrometer PRISMA coupled to the high-resolution Advanced Gamma Tracking Array (AGATA) has been employed. Beamlike reaction products after multinucleon transfer in the Xe region were identified and selected with the PRISMA spectrometer. Coincident particles were tagged by multichannel plate detectors placed at the grazing angle of the targetlike recoils inside the scattering chamber. Results: Mass yields have been extracted and compared with calculations based on the GRAZING model for MNT reactions. Kinematic coincidences between the binary reaction products, i.e., beamlike and targetlike nuclei, were exploited to obtain population yields for nuclei in the actinide region and compared to x-ray yields measured by AGATA. Conclusions: No sizable yield of actinide nuclei beyond Z = 93 is found to perform nuclear structure investigations. In-beam γ -ray spectroscopy is feasible for few-neutron transfer channels in U and the −2p channel populating Th isotopes.

“…However, difficulties exist in modeling these reactions due to their timedependent non-equilibrium nature. The portioning of excitation energy between the final fragments [3,[24][25][26], the amount of irreversible energy dissipation as opposed to excitation of collective modes, conversion of angular momentum to intrinsic spins of the final fragments [27], influence of transfer [23,28,29] have all been subject to experimental [15,[30][31][32] scrutiny with often less than satisfactory comparisons [3,33]. Part of the complication arises from the model dependence of the experimental analysis.…”

Background: The study of deep-inelastic reactions of nuclei provide a vehicle to investigate nuclear transport phenomena for a full range of equilibration dynamics. These inquires provide us the ingredients to model such phenomena and help answer important questions about the nuclear Equation of State (EOS) and its evolution as a function of neutron-to-proton (N/Z) ratio.Purpose: The motivation is to examine the real-time dynamics of nuclear transport phenomena and its dependence on (N/Z) asymmetry from a microscopic point of view to avoid any pre-conceived assumptions about the involved processes.Method: Time-dependent Hartree-Fock (TDHF) method in full 3D is employed to calculate deep-inelastic reactions of 78 Kr+ 208 Pb and 92 Kr+ 208 Pb systems at 8.5 MeV/A. The impact parameter and energy-loss dependence of relevant observables are calculated. In addition, density constrained TDHF method is used to compute excitation energies of the primary fragments. The statistical deexcitation code GEMINI is utilized to examine the final reaction products.Results: The kinetic energy loss and sticking times as a function of impact parameter are calculated. Final properties of the fragments (charge, mass, scattering angle, kinetic energy) are computed. Their evolution as a function of energy loss is studied and various intra-relations are investigated. The fragment excitation energy sharing is computed. Conclusions:We find a smooth dependence of the energy loss, E loss , on the impact parameter for both systems. On the other hand the transfer properties for low E loss values are very different for the two systems but become similar in the higher E loss regime. The mean life time of the charge equilibration process, obtained from the final (N − Z)/A value of the fragments, is shown to be ∼ 0.5 zs. This value is slightly larger (but of the same order) than the value obtained from reactions at Fermi energies.

“…However, extending to the heavy mass domain and even to island of superheavy stability, it is limited by the neutron abundance of projectile-target systems in the fusion-evaporation reactions. The MNT becomes a way to produce the neutron-rich heavy isotopes in nuclear chart [4][5][6].…”

“…The fragment formation in the projectile-like and target-like region was investigated thoroughly. Recently, more measurements have been performed at different laboratories, e.g., the reactions of 136 Xe+ 208 Pb [34,35], 136 Xe+ 198 Pt [36], 156,160 Gd+ 186 W [37], 238 U+ 232 Th [38]. It has been shown that the MNT reactions are feasible for producing new isotopes.…”

Approaching the neutron-rich heavy and superheavy nuclei by multinucleon transfer reactions with radioactive isotopes

The dynamical mechanism of multinucleon transfer (MNT) reactions has been investigated within the dinuclear system (DNS) model, in which the sequential nucleon transfer is described by solving a set of microscopically derived master equations. Production cross sections, total kinetic energy spectra, angular distribution of formed fragments in the reactions of 124,132 Sn+ 238 U/ 248 Cm near Coulomb barrier energies are thoroughly analyzed. It is found that the total kinetic energies of primary fragments are dissipated from the relative motion energy and rotational energy of the two colliding nuclei. The fragments are formed in the forward angle domain. The energy dependence of the angular spectra is different between projectile-like and target-like fragments. Isospin equilibrium is governed under the potential energy surface. The production cross sections of neutron-rich isotopes are enhanced around the shell closure.PACS number(s): 25.70. Jj, 25.60.Pj
