Fission in238U+238U collisions below the Coulomb barrier

1988

Integral fission cross sections in the system238U+238U were measured at beam energies below the interaction barrierVC. Scattering angle dependent probabilities and integral cross sections for Coulomb fission were calculated. It is concluded that earlier observed discrepancies between measured and calculated angular distributions for the one-neutron transfer product239U cannot be explained by sequential fission. Multi-nucleon transfer induced fission is observed down to energies (0.90±0.02)×VC.
