Study of the Possibility of Obtaining Neutron-Enriched Isotopes with the Magic Number N = 126 in the Multinucleon Transfer Reactions Induced by Radioactive Ion Beams

In this work, the theoretical analysis of the yields of heavy neutron-enriched isotopes with the magic number $$N = 126$$ obtained in the multinucleon transfer reactions $$^{{132}}$$ Sn, $$^{{136, 138, 140}}$$ Xe + $$^{{198}}$$ Pt is presented. Calculations have been carried out within the multidimensional dynamic model based on Langevin equations, which describes well enough the available experimental data on the $$^{{136}}$$ Xe + $$^{{198}}$$ Pt reaction with the stable projectile $$^{{136}}$$ Xe. The use of neutron-enriched radioactive projectiles $$^{{132}}$$ Sn, $$^{{138, 140}}$$ Xe in multinucleon transfer reactions with the $$^{{198}}$$ Pt target leads to an increase in the production cross section of neutron-enriched heavy nuclides.
