Production of neutron-rich actinide isotopes in isobaric collisions via multinucleon transfer reactions
Listed in ScienceDB
We systematically calculated the multinucleon transfer reactions of 208Os, 208Pt, 208Hg, 208Pb,208Po, 208Rn, 208Ra, and 132,136Xe when bombarded on 232Th and 248Cm at Coulomb barrier energies within the dinuclear system model.
Description
These results are in good agreement with the available experimental data. The influence of Coulomb and shell effects on actinide production in these reactions has been rigorously studied.
We calculated and analyzed the potential energy surface (PES) and total kinetic energy (TKE) mass distributions for the reactions involving 208Hg, 208Pb, and 208Po with 248Cm and 232Th. The PES and TKE spectra shed light on the fragment formation mechanisms in multinucleon transfer reactions, with clear indications of isospin and shell effects. The production cross-sections for multinucleon transfer products show a strong dependence on isobar projectiles with a mass number A = 208.

Isobar projectiles with high N/Z ratios are advantageous for generating neutron-rich target-like fragments. Conversely, products induced by isobar projectiles with larger charge numbers tend to shift toward proton-rich regions. The intertwining of the Coulomb potential and shell effect is evident in the production cross-sections of actinide isotopes.
Drawing from reactions induced by radioactive projectiles, we anticipate the discovery of several new actinide isotopes near the nuclear drip lines, extending our reach into the superheavy nuclei domain.
