“…First of all it is a threshold reaction with a (or even several) strong vibrational resonances at the threshold of the fission cross section. As it seems to be the case also for other isotopes around these vibrational resonances in the fission cross section threshold the properties of the fission fragments are changing as it has been found in the work of Goverdovskii [1]. However, in a similar experiment on 238 U(n,f) the previously observed fluctuations in literature of the fission fragment properties in the vibrational resonances in the fission cross section threshold could not be verified [2].…”

“…08001-p.8 Figure 10 shows the mean TKE as a function of incident neutron energy compared to Ref. [1]. The absolute mean TKE values are close to the ones of 235 U(n,f) [9] except around the vibreational resonance region.…”

Abstract.The fission fragment properties of 234 U(n,f) were investigated as a function of incident neutron energy from 0.2 MeV up to 5 MeV. The fission fragment mass, angular distribution and kinetic energy were measured with a double Frisch-grid ionization chamber using both analogue and digital data acquisition techniques. The reaction 234 U(n,f) is relevant, since it involves the same compound nucleus as formed after neutron evaporation from highly excited 236 U*, the so-called second-chance fission of 235 U. Experimental data on fission fragment properties like fission fragment mass and total kinetic energy (TKE) as a function of incident neutron energy are rather scarce for this reaction. For the theoretical modelling of the reaction cross sections for Uranium isotopes this information is a crucial input parameter. In addition, 234 U is also an important isotope in the Thorium-based fuel cycle. The strong anisotropy of the angular distribution around the vibrational resonance at E n = 0.77 MeV could be confirmed using the full angular range. Fluctuations in the fragment TKE have been observed in the threshold region around the strong vibrational resonance at E n = 0.77 MeV. The present results are in contradiction with corresponding literature values. Changes in the mass yield around the vibrational resonance and at E n = 5 MeV relative to E n = 2 MeV show a different signature. The drop in mean TKE around 2.5 to 3 MeV points to pair breaking as also observed in 235,238 U(n,f). The measured two-dimensional mass yield and TKE distribution have been described in terms of fission modes. The yield of the standard 1 (S1) mode shows fluctuations in the threshold of the fission cross section due to the influence of the resonance and levels off at about 20% yield for higher incident neutron energies. The S2 mode shows the respective opposite behaviour. The mean TKE of both modes decreases with E n . The decrease in mean TKE overrules the increase in S1 yield, so the mean TKE is dropping as a function of E n above 2.5 MeV.

Three models of the sonoluminescence source formation are considered: the shock free compres sion model, the shock wave model, and the polarization model. Each of them is tested by experimental data on the size of the radiating region and the angular radiation pattern; the shape and duration of the radiation pulse; the influence of the type of liquid, gas composition, surfactants, sound frequency, and temperature of the liquid on the radiation intensity; the characteristics of the shock wave in the liquid; and the radiation spec tra. It is shown that the most adequate qualitative explanation of the entire set of experimental data is given by the polarization model. Methods for verifying the model are proposed. Publications devoted to studying the possibility a thermonuclear fusion reaction in a cavitation system are reviewed.
