Abstract
Low energy collisions of very heavy nuclei (238U+238U, 232Th+250Cf and 238U+248Cm) have been studied within the realistic dynamical model based on multi‐dimensional Langevin equations. Large charge and mass transfer was found due to the “inverse quasi‐fission” process leading to formation of survived superheavy long‐lived neutron‐rich nuclei. In many events lifetime of the composite system consisting of two touching nuclei turns out to be rather long; sufficient for spontaneous positron formation from super‐strong electric field, a fundamental QED process.
