Transfer-induced fission of superheavy nuclei

Advantages of the multinucleon transfer reactions based on 238U target for producing neutron-rich isotopes around N = 126

“…In Refs. [5,[11][12][13], it was found that due to N/Z equilibration, the projectiles with large neutron excesses show great advantage of production cross sections of neutronenriched transtarget nuclei. For radioactive beams, although the neutron excesses are large, the beam intensities are usually * zhulong@mail.sysu.edu.cn lower than stable ones.…”

Production cross section of neutron-rich isotopes with radioactive and stable beams

“…The quasifission and transfer products result from the decays of various DNS configurations. The DNS is formed at the capture stage of the reaction after complete dissipation of the kinetic energy of the relative motion [15,16,[20][21][22][23][24]. The dynamics of the process is considered as a diffusion of the DNS in the charge and mass asymmetry coordinates, which are defined by the charge and neutron numbers Z and N , respectively, of the light or heavy nucleus of the DNS.…”

“…In the present paper, by extending the work of Ref. [16], we investigate the production of various neutron-rich isotopes and study other possible reactions for the production of the isotopes previously considered.…”

“…However, in the fragmentation reactions, the yields of these nuclei decrease with increasing isospin quantum number and a large excitation energy is available, which can wash out the primary yields of extremely neutron-rich nuclei. On the other hand, the neutron-rich nuclei can be also effectively produced in the transfer-type reactions in which the control of excitation energy is easier [4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

Microscopic dynamics simulations of multinucleon transfer inKr86+Ni64at 25 MeV/nucleon

“…To investigate the MNT processes theoretically, the semiclassical GRAZING model [41,42] has been developed with great successes [43]. In addition, a dynamical model based on Langevin-type equations [44] and the dinuclear system (DNS) model [45][46][47] are also proposed to describe the nucleon transfer process. To understand the dynamical nucleon transfer process in fusion and deep inelastic scattering reactions more microscopically, some microscopical dynamics models, such as TDHF [48][49][50][51][52] and the ImQMD model [53][54][55][56] have also been developed.…”
