Abstract
The fusion of with has been studied at energies close to and below the Coulomb barrier. The experiment was carried out at the Dubna Radioactive Ion Beams complex of FLNR, JINR. The beam intensity was about , the maximum energy being . The yield of the isotope, produced in the -evaporation channel, demonstrates an extremely large enhancement of the sub-barrier fusion cross section as compared with the reaction. This enhancement is most likely due to the mechanism of “sequential fusion” with an intermediate neutron transfer from to the Pb nucleus with positive values.
