A general description of the fission mechanism considers both microscopical quantities, such as nuclear structure of the fission fragments, and macroscopic effects, like the Coulomb repulsion between the nuclei. The interplay between both quantities prevents, so far, from a fully microscopical description of the interaction. Despite the development of different theoretical models [1] and...

Accurate modelling of nuclear fragmentation is essential in ion beam therapy, where secondary ions contribute significantly to dose deposition and biological effects. However, the predictive capabilities of current Monte Carlo models remain limited in the energy range of therapeutic beam, especially for light fragment production (Z = 1–6), due to a lack of experimental data.

The stability of nuclei beyond the spherical double shell closure of $^{208}$Pb rapidly decreases because of the disappearance of the macroscopic fission barrier. This phenomenon is however compensated by quantum shell effects caused by alternating zones of high and low densities caused by deformation.

The p-process was first proposed as a solution to the formation of proton-rich heavy nuclei between Se and Hg that cannot be produced via the r- and s-processes. The p-nuclei are typically 10-1000 times less abundant than isotopes formed through the r or s-processes, making the study of their reaction cross-sections fundamental for improving current nucleosynthesis models [1]. In this work, I...

In the last decade, SiC-based detectors have emerged as strong candidates for next-generation particle detection. This is due to several advantageous properties of the material, including its high breakdown field, high saturation velocity, wide band-gap, radiation hardness, strong mechanical resistance, and thermal stability [1–3]. Additionally, SiC has been proposed as a promising solution...

Abstract: The accurate determination of reactor antineutrino spectra remains a very actual research topic for which interrogations have emerged in the past decade. Indeed, after the “reactor anomaly” (RAA) [1] – a deficit of measured antineutrinos at short baseline reactor experiments with respect to spectral predictions – the three international reactor neutrino experiments Double Chooz, Daya...

Over the past few years, there has been an increasing interest in exotic nuclear shapes and accompanying symmetries in low energy subatomic physics, both from theory and experimental points of view. We are going to address theoretical calculations employing realistic nuclear structure Hamiltonians to provide trustworthy predictions of the still unknown quantum mechanisms; new concepts are also...

The appearance of a subshell closure in $^{56}$Cr (N=32) is confirmed by the high excitation energy of the 2$_{1}^{+}$ state and the B(E2;2$_1^+\rightarrow$0$_1^+$). Shell model calculations are able to reproduce the energy of the first 2$^+$ state but not the drop of collectivity at N=32 for the Cr isotopes.

Neutron capture reactions play an important role in nuclear astrophysics as they are at the base of the s-process and the r-process, the two main mechanisms of nucleosynthesis beyond the iron peak.

Neutron capture cross sections are therefore important inputs of stellar models. Their accurate knowledge is crucial to predict reliable stellar yields and isotopic abundances that, compared with... -

The study of reactions involving weakly bound exotic nuclei is an active field due to advances in radioactive beam facilities. Many of these nuclei can be approximately described by a model consisting of an inert core and one or more valence nucleons. However to properly describe some of these nuclei within few-body models, additional effects must be considered, such as deformations and...

FAIR (Facility for Antiproton and Ion Research) is an international accelerator facility under construction at the site of the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.FAIR will deliver a wide range of intense primary and secondary beams at relativistic energies, including radioactive beams of all elements and, in a later stage, antiprotons.
The existing GSI accelerators...

The ab initio method in nuclear theory can be interpreted as a systematically improvable approach for quantitatively describing nuclei using the finest resolution scale possible while maximizing its predictive capabilities. In this talk, I will highlight some recent developments in ab initio nuclear structure calculations, focusing on the use of Bayesian methods for uncertainty quantification....

Human activities—whether nuclear (civilian and military) or industrial processes involving naturally radioactive materials (oil and gas production, phosphate mining, and rare earth extraction)—have released and redistributed radionuclides across environmental compartments. This contamination could threaten ecosystems and human health, with risks driven by the persistence, concentration, and...

In this talk, I will review the unique place the Sun has as a fundamental laboratory for astrophysics and related fields. I will put the emphasis on current open questions and, in relation to them, on the need for accurate measurements of key nuclear reaction cross sections.

A rich spectrum of giant resonances of different multipolarities and spin and isospin structure was expected on theoretical grounds. In the nineteen seventies, the isoscalar giant quadrupole resonance (ISGQR) was discovered in electron scattering followed by the isoscalar giant monopole resonance (ISGMR) in inelastic $\alpha$ scattering. In the last five decades, the compression modes the...

The magnetic dipole scissors mode and its implications for the low-energy structure of heavy nuclei are discussed. Salient features like its orbital nature, the correlation of the strength with ground-state deformation, the collectivity and a systematic description within a sum-rule approach are reviewed [1]. The scissors mode is also observed in the quasicontinuum and may be related to the...

Simulations of explosive nucleosynthesis in novae predict the production of the radioisotope 22Na. Its half-life of 2.6 yr makes it a very interesting astronomical observable by allowing space and time correlations with the astrophysical object. Its 𝛾-ray line at 1.275 MeV has not been observed yet by 𝛾-ray space observatories. This radioisotope should bring constraints on nova models and help...

Infinite nuclear matter lies at the crossroads of nuclear physics investigations, as it connects the microscale of nuclei and the macroscale of compact celestial bodies. On the one hand, nuclear matter properties can be partially constrained by finite nuclei observables and astrophysical observations. On the other hand, nuclear matter can guide the development of both ab initio nuclear...

The radioisotope thorium-229 features a nuclear isomer with an exceptionally low excitation energy of ≈ 8.4 eV and a favorable coupling to the environment, making it a candidate for a next generation of optical clocks allowing to study fundamental physics such as the variation of the fine structure constant [1,2].
