Abstract

Background: The nature of asymmetric fission of preactinides is not yet understood in detail, despite intense experimental and theoretical studies carried out at present. Purpose: The study of asymmetric and symmetric fission of Hg180,182,183 and Pt178 nuclei as a function of their excitation energy and isospin. Methods: Mass-energy distributions of fission fragments of Hg180, Pt178 (two protons less than Hg180), and Hg182 (two neutrons more than Hg180) formed in the Ar36+Sm144, Nd142, and Ca40+Nd142 reactions were measured at energies near and above the Coulomb barrier. Fission of Hg183 obtained in the reaction of Ca40 with Nd143 was also investigated to see if one extra neutron could lead to dramatic changes in the fission process due to the shape-staggering effect in radii, known in Hg183. The measurements were performed with the double-arm time-of-flight spectrometer CORSET. Results: The observed peculiarities in the fission fragment mass-energy distributions for all studied nuclei may be explained by the presence of a symmetric fission mode and three asymmetric fission modes, manifested by the different total kinetic energies and fragment mass splits. The yield of symmetric mode grows with increasing excitation energy of compound nucleus. Conclusions: The investigated properties of asymmetric fission of Hg180,182,183 and Pt178 nuclei point out the existence of well-deformed proton shell at Z≈36 and a less deformed proton shell at Z ≈ 46.

Abstract

The dependence of the properties of the fission fragments formed both in the fusion-fission and fast fission processes on the angular momentum still remains very unclear from an experimental as well as theoretical point of view. To study the properties of fast fission fragments of preactinide nuclei as function of the interaction energy and introduced angular momentum, the mass-energy distributions of Pb fission fragments formed in the Sm reaction at energies above the Coulomb barrier have been measured using the double-arm time-of-flight spectrometer CORSET at the Ca ions' energies of 212, 231, 244, and 277 MeV. The mass-energy distributions of the fast fission fragments have been extracted by subtracting the mass-energy matrices corresponding to the compound nucleus fission from those of all measured fissionlike events. The asymmetric fragments with masses 76 and 108 u were found to be the most probable in the fast fission of Pb. With increasing Ca energy from 231 to 277 MeV the mass distributions of fast fission fragments change weakly, whereas an increase in the TKE is about 20 MeV. The properties found for the fast fission fragments indicate the incomplete mass relaxation and not full energy dissipation. [ABSTRACT FROM AUTHOR]

Abstract

Mass–energy distributions of binary fragments produced in the Zr reaction at the projectile-ion energy of 378 MeV were measured by means of the CORSET double-arm time-of-flight spectrometer. From a comparison of the mass–energy distributions measured in the present study with the distributions of fragments produced in the Sm and Sn reactions leading to the formation of the same compound system Hg, it was found that the contribution of the fusion–fission process involving a compound nucleus to the total distribution of fission-like fragments was less than 20 .

Abstract

The role of closed and deformed proton and neutron shells in the fission of Cf and Fm nuclei at excitation energies from 40 to 56 MeV is studied. The mass–energy distributions of fission fragments of these nuclei formed in the Th and U reactions at projectile-ion energies close to the Coulomb barrier are measured by means of the CORSET time-of-flight spectrometer. It is shown that, in all of the reactions under study, an enhanced yield of fragments in the mass region around 100 a.m.u. is due to the effect of the deformed proton shell. A manifestation of a supershort mode is found in the fission of Fm at the compound-nucleus excitation energy of 40 MeV. [ABSTRACT FROM AUTHOR]
