Dissipation Model

The fusion-fission process for the synthesis of superheavy elements is discussed on the basis of fluctuation-dissipation model. We employ three-dimensional Langevin equation. We investigate the fusion-fission process by analyzing not only the mass distribution of fission fragments but also neutron multiplicity on fusion-fission process.

We analyzed experimental data obtained for the mass distribution of fission fragments in the reactions 36 S +238 U and 30 Si +238 U at several incident energies, which were performed by the JAEA group. Using the dynamical model with the Langevin equation, we precisely investigate the incident energy dependence of the mass distribution of fission fragments. We also consider the fine structures in the mass distribution of fission fragments caused by the nuclear structure at a low incident energy. It is explained why the mass distribution of fission fragments has different features in the two reactions. The fusion cross sections are also estimated.

Improved radiochemical techniques have been used to study the distribution in mass of the fission fragments resulting from thermal neutron fission in 239Pu.Disintegration rates and half-lives were determined by measurement with a 4πβ gas flow proportional counter. Further identification of the nuclides was obtained by gamma scintillation spectrometry. The flux intensity during irradiation was monitored by the 59Co(n,γ)60Co reaction.The absolute fission yields of 89Sr, 90Sr, 91Y, 95Zr, 99Mo, 103Ru, 106Ru, 105Rh, 109Pd, 1I2Pd, 111Ag, and 115Cd in the light mass peak and 127Sb, 131I, 133I, 132Te, 137Cs, 140Ba, 141Ce, 143Ce, 144Ce, 147Nd, and 156Eu in the heavy mass peak have been measured. In addition, the independent yields of 82Br, 124Sb, 126Sb, and 136Cs were obtained.
