Multinucleon transfer mechanism in the collision of
238U+238U system is investigated at Ec.m.​=833 MeV in the framework of the quantal diffusion description based on the
stochastic mean-field approach (SMF). 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 238U+238U system may be located at an unstable
equilibrium state at the potential energy surface with a slightly negative
curvature along the beta stability line on the (N,Z)−plane. This behavior may
lead to rather large diffusion along the beta stability direction.Comment: 10 pages, 10 figures. arXiv admin note: text overlap with
