Özet

© 2020 American Physical Society.Multinucleon transfer mechanism in the collision of U238+U238 system is investigated at Ec.m.=833 MeV in the framework of the quantal diffusion description based on the stochastic mean-field approach. Double cross sections σ(N,Z) as a function of the neutron and proton numbers, the cross sections σ(Z) and σ(A) as a function of the atomic numbers and the mass numbers are calculated for production of the primary fragments. The calculation indicates the U238+U238 system may be located at an unstable equilibrium state at the potential energy surface with a slightly negative curvature along the β stability line on the (N,Z) plane. This behavior may lead to rather large diffusion along the β stability direction.
