Fission and Quasi-Fission of Nuclei Produced in the Reactions with 48CA Ions
Abstract
The work presents the results of the study of characteristics of the fission and quasi-fission of heavy nuclei, produced in the reactions with 48Ca ions at energies close to and below the Coulomb barrier. These experiments have been performed at the U-400 accelerator of the Flerov Laboratory of Nuclear Reactions (JINR) and XTU tandem accelerator in Legnaro (Italy) with the use of the fission fragments time-of-flight spectrometer CORSET and neutron multidetector DEMON. Mass-energy distributions of the 48Ca+ 168Er, 208Pb, 238U reaction products have been studied. The pre- and post-fission neutron multiplicities as a function of the fragment mass have been studied for the two heavier systems. A strong manifestation of shell effects has been found in mass-energy distributions for all the reactions in study.
