The ${}^{33}\mathrm{S}(n,\alpha ){}^{30}\mathrm{Si}$ cross section has been measured at the neutron time-of-flight ($\mathrm{n}\_\mathrm{TOF}$) facility at CERN in the neutron energy range from 10 to 300 keV relative to the ${}^{10}\mathrm{B}(n,\alpha ){}^7\mathrm{Li}$ cross-section standard. Both reactions were measured simultaneously with a set of micromegas detectors. The flight path of 185 m has allowed us to obtain the cross section with high-energy resolution. An accurate description of the resonances has been performed by means of the multilevel multichannel $R$-matrix code sammy. The results show a significantly higher area of the biggest resonance (13.45 keV) than the unique high-resolution ($n,\alpha$) measurement. The new parametrization of the 13.45-keV resonance is similar to that of the unique transmission measurement. This resonance is a matter of research in neutron-capture therapy. The ${}^{33}\mathrm{S}(n,\alpha ){}^{30}\mathrm{Si}$ cross section has been studied in previous works because of its role in the production of ${}^{36}\mathrm{S}$ in stars, which is currently overproduced in stellar models compared to observations.

The International Fusion Materials Irradiation Facility - Demo Oriented NEutron Source (IFMIF-DONES) is a single-sited novel Research Infrastructure for testing, validation and qualification of the materials to be used in a fusion reactor. Recently, IFMIF-DONES has been declared of interest by ESFRI (European Strategy Forum on Research Infrastructures) and its European host city would be Granada (Spain). In spite the first and most important application of IFMIF-DONES related to fusion technology, the unprecedented neutron flux available could be exploited without modifying the routine operation of IFMIF-DONES. Thus, it is already planned an experimental hall for a complementary program with neutrons. Also, a complementary program on the use of the deuteron beam could help IFMIF-DONES to be more sustainable. In the present work, we study radioisotope production with deuterons of ¹⁷⁷Lu. The results show the viability of IFMIF-DONES for such production in terms of the needs of a territory of small-medium size. Also the study suggests that new nuclear data at higher deuteron energies are mandatory for an accurate study in this field.

Boron Neutron Capture Therapy (BNCT) is performed using high-intensity neutron sources; however, the energy of the primary neutrons is too high for direct patient irradiation. Thus, neutron moderation is mandatory and is performed using a device known as a Beam Shaping Assembly (BSA). Due to the differences in flux and energy spectra between neutron sources, each facility needs a dedicated BSA design, whether it is based on a nuclear reactor or, more recently, on an accelerator. Since moderation involves the loss of neutrons, typically by a factor of 1000, it is necessary to generate a very high flux before neutrons pass through the BSA. We propose a novel approach that eliminates the necessity of a BSA, BSA-free, by generating neutrons suitable in flux and energy for direct patient irradiation through the \({}^{45}\)Sc(p,n)\({}^{45}\)Ti reaction using near-threshold protons. Our findings demonstrate that all IAEA quality factors for BNCT can be met with existing proton accelerators. Additionally, figures of merit studied provide similar results compared to real BNCT facilities. This breakthrough opens up new avenues in BNCT, among others, the control of the neutron penetration within the human body by small changing in the proton energy. Also, it is expected simplified accelerator-based facilities in terms of manufacturing and maintenance and operation. This work is a study based on experimental data and Monte Carlo simulations. Technical challenges and safety are addressed in Discussion section. This novel proposal is under evaluation as patent.

Linearized state-dependent and central Jastrow correlated trial wavefunctions are used to study the ground state of spin-isospin saturated p-shell nuclei with V4-type forces. We extend the variational Monte Carlo method to incorporate this kind of operatorial correlation by introducing only minor changes with respect to the case of central correlations. Very good energies are obtained with this wavefunction for the nuclei studied. Finally, a discussion of the role of the different correlation mechanisms included in this trial wavefunction is performed in terms of both the momentum distribution and the one- and two-particle densities in position space.
