Abstract

Angular correlations and angular distributions of the fission fragments produced in the bombardment of a ²³²Th target with protons, deuterons and α-particles in the energy range between 35 and 1000 MeV/nucleon have been measured. From these measurements, the distributions of linear momentum imparted to fissioning nuclei have been deduced in the various energy regimes; dominating reaction mechanisms are classified according to the fraction of the available incident momentum transferred to the target. The experimental results are compared to the predictions of intra-nuclear cascade calculations. An optimum excitation energy supported by the fissioning nuclei could be the dominant limitation to momentum transfer at high incident energies. The angular distributions of the fission fragments were used to extract fission cross sections and upper limits of the angular momentum imparted to the fissioning nuclei.

Transmutation of uranium and thorium in the particle field of the Quinta sub-critical assembly
2018, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment

Above 1 GeV, the cross section was assumed to remain constant, maintaining the end value of the fitted polynomial. There is very limited experimental data available for U(d, f) and Th(d, f) and the data that is available have large uncertainties [42,43]. Therefore, the parametrised proton-induced fission cross sections were normalised to the experimental data of the deuteron (Fig. 9).
The fission rates of natural uranium and thorium were measured in the particle field of Quinta, a 512 kg natural uranium target–blanket sub-critical assembly. The Quinta assembly was irradiated with deuterons of energy 4 GeV from the Nuclotron accelerator of the Joint Institute for Nuclear Research (JINR), Dubna, Russia. Fission rates of uranium and thorium were measured using Gamma spectroscopy and fission track techniques. The production rate of ²³⁹Np was also measured. The obtained experimental results were compared with Monte Carlo predictions using the MCNPX 2.7 code employing the physics and fission–evaporation models of INCL4–ABLA, CEM03.03 and LAQGSM03.03. Some of the neutronic characteristics of the Quinta are compared with the “Energy plus Transmutation (EpT)” subcritical assembly, which is composed of a lead target and $^{nat}$ U blanket. This comparison clearly demonstrates the importance of target material, neutron moderator and reflector types on the performance of a spallation neutron driven subcritical system.
As the dimensions of the Quinta are very close to those of an optimal multi-rod-uranium target, the experimental and Monte Carlo calculation results presented in this paper provide insights on the particle field within a uranium target as well as in Accelerator Driven Systems in general.
Synthesis of neutron-rich transuranic nuclei in fissile spallation targets
2015, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms
A possibility of synthesizing neutron-rich superheavy elements in spallation targets of Accelerator Driven Systems (ADS) is considered. A dedicated software called Nuclide Composition Dynamics (NuCoD) was developed to model the evolution of isotope composition in the targets during a long-time irradiation by intense proton and deuteron beams. Simulation results show that transuranic elements up to ²⁴⁹Bk can be produced in multiple neutron capture reactions in macroscopic quantities. However, the neutron flux achievable in a spallation target is still insufficient to overcome the so-called fermium gap. Further optimization of the target design, in particular, by including moderating material and covering it by a reflector could turn ADS into an alternative source of transuranic elements in addition to nuclear fission reactors.
Fission induced by nucleons at intermediate energies
2015, Nuclear Physics A
Monte Carlo calculations of fission of actinides and pre-actinides induced by protons and neutrons in the energy range from 100 MeV to 1 GeV are carried out by means of a recent version of the Liège Intranuclear Cascade Model, INCL++, coupled with two different evaporation-fission codes, GEMINI++ and ABLA07. In order to reproduce experimental fission cross sections, model parameters are usually adjusted on available $(p, f)$ cross sections and used to predict $(n, f)$ cross sections for the same isotopes.
Spatial distribution of thorium fission rate in a fast spallation and fission neutron field: An experimental and Monte Carlo study
2012, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
The Energy plus Transmutation (EpT) set-up of the Joint Institute for Nuclear Research (JINR), Dubna, Russia is composed of a lead spallation target surrounded by a blanket of natural uranium. The resultant neutron spectrum is a combination of spallation and fission spectra, modified by a reflective external layer of polyethylene and an internal absorbing layer of cadmium. The EpT set-up was irradiated with a beam of 4 GeV deuterons from the Nuclotron Accelerator at JINR. The spatial distribution of thorium fission rate within the assembly was determined experimentally, using a fission track detector technique, and compared with Monte Carlo predictions of the MCNPX code. Contributions of neutrons, protons, deuterons, photons and pions to total fission were taken into account. Close agreement between the experimental and calculated results was found.
The theoretical calculation of p+<sup>232</sup>Th reaction for energies up to 250 MeV

The experimental data of fission cross sections were given in different laboratories, and there are significant differences. The calculated results are in good agreement with the experimental data taken from Refs. [27–29] as shown in Fig. 5. The calculated results are similar to the results of systematics taken from Ref. [30].
All reaction cross sections, energy spectra and double differential cross sections of neutron, proton, deuteron, triton, and alpha-particle emission for p+²³²Th reaction are consistent calculated and analyzed with the optical model, the intranuclear cascade model, the unified Hauser–Feshbach theory and the exciton model which included the improved Iwamoto–Harada model, the fission model and the distorted wave Born approximation theory in the energy range of $E_{p} ⩽ 250 MeV$ . Theoretical calculations are compared with existing experimental data.
Symmetric vs asymmetric nucleon-induced fission of thorium up to 200 MeV
2007, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
The transition from asymmetric to symmetric fission as dependent on the excitation energy and nucleon composition of fissioning Th and Pa nuclei is investigated for the ²³²Th(n, F) and ²³²Th(p, F) reactions, respectively. Observed neutron-induced fission cross sections are described in a fission/evaporation approximation. A separate relatively high outer fission barrier $E_{f B}^{SL}$ with significant curvature was assumed for the symmetric mode, while the inner one ( $E_{f A}^{SL (AS)}$ ) was assumed to be the same for symmetric $(SL)$ and asymmetric $(AS)$ modes. Axial asymmetry and mass symmetry is assumed for the outer saddle of the SL-mode, as distinct from the AS-mode. A drop of $(E_{f A}^{SL} - E_{f A}^{AS}) = 3.5 MeV$ to ∼1–1.5 MeV for Th and Pa nuclei with $A ⩽ 226$ is responsible for the increase of the symmetric fission contribution to ^{225,229,230,231,232}Th(n, F) or ²³²Th(p, F) fission cross sections with nucleon energy up to $E_{n (p)} = 200 MeV$ . It is shown that with increase of the $E_{n (p)}$ above $\sim 80 MeV$ the ^{229,230,231,232}Th(n, F) fission cross sections are no longer dependent on the Th target nuclide fissility. The dependence of ²³²Th fission cross section on the incident particle (n or p) is predicted to be different than in case of ²³⁸U target nuclide.
