“…It models spallation targets taking into account the time evolution of their composition due to primary and secondary nuclear interactions and radioactive decays including nuclear reactions on spallation products. NuCoD was validated against available experimental data on nuclide composition in a Pb spallation target after its irradiation by a proton beam [23] and also against recently measured total cross sections of deuteron-induced fission of 232 Th and 238 U [18,20].…”

“…In order to illustrate a general trend of the total fission cross section as a function of beam energy the following analytical parametrization of r df from Ref. [18]: [16][17][18] for 232 Th and [16,19,20] is also shown in Fig. 1.…”

“…Nevertheless, since the deuteron-induced fission of target nuclei is one of the key processes of neutron production, we have performed MCADS simulations to find the fractions of fission events in thin actinide targets irradiated by deuterons. The total deuteron-induced fission cross sections r df were estimated from these simulations and compared with the respective experimental data for 232 Th [16][17][18] and 238 U [16,19,20] nuclei in Fig. 1.…”

a b s t r a c tA 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 249 Bk 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.

“…In recent years, due to the applications in Accelerator Driven Systems, fission research has been extended to higher energies, at GeVs. However, limited experimental data have been presented in the literature regarding deuteron projectiles [17][18][19] and even less for alpha particles [20], although they are very useful for the comparison of the experimental data to both statistical and dynamical models of fission [2]. Some of those results, referring to high energy deuterons on actinide and sub-actinide targets [17,19] were obtained during experiments at the NUCLOTRON accelerator; JINR, Dubna, in the frame of the international collaboration "Energy plus Transmutation" [21].…”

Total fission cross sections induced by deuterons with energies 1.6, 2.5 and 4.0 GeV on 232Th targets and by protons on natPb targets at energy 2.0 GeV were measured during irradiations at the Nuclotron accelerator, JINR, Dubna. Using Solid State Nuclear Track detectors, the fission cross sections induced by deuterons on 232Th were determined as 1277±216, 1232±207 and 1153±198 mb, corresponding to the energies mentioned above. The total fission cross section of protons on natPb was estimated by the same method as 131±30 mb. These results were compared to the previous systematic parameterization of proton induced fission and new values for the parameters of deuteron-induce fission on actinides, 232Th and 238U and proton induced fission on natPb were deduced. Fitting results obtained for deuterons on actinides are discussed and compared to results for protons.

“…The nuclear fission and spallation phenomena have been studied by several methods and techniques, including direct and inverse kinematics [6][7][8][9][10][11][12]. In these studies the basic mechanism, responsible for the development of various processes that usually occur during the interaction between intermediate-and high-energy projectiles and heavy nuclei targets, has been determined.…”

The induced-activity investigations in off-line analysis performed in different experiments, concerning pre-actinide and actinide nuclei, are here presented and discussed. Generalized expressions for the determination of independent yields/cross sections of radioactive nuclei, formed in the targets, are derived and analysed. The fragment mass distribution from 238 U, 232 Th and 181 Ta photofission at the bremsstrahlung end-point energies of 50 and 3500 MeV, and from 241 Am, 238 U and 237 Np fission induced by 660-MeV protons, are scrutinized from the point of view of the multimodal fission approach. The results of these studies are hence compared with theoretical model calculations using the CRISP code. A multimodal fission option has been added to this code, which allows to account the contribution of symmetric and asymmetric (superasymmetric) fission to the total fission yield. Moreover, this work contains the general results obtained in the analysis of the isomer ratios of fission fragments from 238 U and 232 Th targets at the bremsstrahlung end-point energies of 50 and 3500 MeV. Moreover, the values of the average angular momenta of primary fragments are estimated by using the statistical model calculation. We subsequently discuss the complex particle-induced reaction, such as heavy-ions and deuterons, by using the thick-target thick-catcher technique and the two-step vector model framework as well. This is accomplished in order to present the investigation of the main processes (fission, spallation and (multi)fragmentation) in intermediate-and high-energy ranges of the incident particle. The set of experimental data, presented in this work, encompasses not merely the data as total production cross sections. Notwithstanding, it further covers other data, as individual yields/cross sections, charge, mass and spin distributions of the reaction fragments, as well as kinematic features. These sources of experimental data can serve as a consistent set of benchmarking data, still necessary for the study of heavy nuclei. Besides, it is also useful for technological applications, from astrophysics and environmental sciences to accelerator technology and accelerator-based nuclear waste transmutation and energy amplification as well.
