The complex nature of the nucleon-nucleon interaction allows for spherical, oblate and prolate deformations to appear at similar energies within the same nucleus. This phenomenon, known as shape coexistence, is widespread across the nuclear chart and it provides a crucial role in understanding nuclear structure [1].

In our study we complement shell-model calculations [2] with...

Time-dependent density functional theory (TDDFT) provides a fundamental framework for describing nuclear collective time-dependent processes, ranging from small-amplitude collective oscillations to large-amplitude phenomena such as fission and heavy-ion reactions. However, due to its mean-field nature, TDDFT accounts only for one-body dissipation effects and fails to describe the spreading...

The isomeric cross-section ratio R = σm/σg for the ¹⁹⁷Au(p,n)¹⁹⁷m,gHg reaction is analyzed over the proton energy range 6.5–32.0 MeV using selected published experimental datasets retrieved from the EXFOR nuclear reaction database and primary publications. Cross-sections calculated with the TALYS-1.9 nuclear reaction code, taken from the TENDL-2019 evaluated nuclear data library (Plompen et...

Coulomb-excitation measurements provide a direct and model-independent probe of electromagnetic matrix elements, which are essential for understanding collective motion, shape coexistence, and configuration mixing in atomic nuclei [1]. The extraction of these quantities relies on a global least-squares analysis of experimental γ-ray yields against calculated excitation probabilities, where the...

Accurate neutron-capture and photodisintegration reaction rates obtained within the Hauser-Feshbach statistical framework depend critically on the nuclear $\gamma$-ray strength function and nuclear level density. Uncertainties in these quantities propagate directly into Maxwellian-averaged cross sections and remain a major source of uncertainty in modeling $r$-process nucleosynthesis. In this...

Decoherence leads to the loss of quantum correlations in entangled systems due to interactions with surrounding matter. While entanglement and its decoherence is well established in the optical photonic regime, its behaviour at the MeV energy scale, such as $\gamma$-ray pairs produced in positron annihilation, is far less well established and with only limited experimental evidence to...

Deuteron–deuteron fusion at very low energies is relevant both for nuclear astrophysics and for prospective fusion-energy applications [1]. The reaction cross section decreases sharply with decreasing projectile energy due to the Coulomb barrier; however, in metallic targets, electron screening significantly enhances the barrier penetration probability [2]. Recent studies have suggested that...

The doubly magic nucleus $^{208}$Pb is the archetypal heavy ion system. Yet, there are unresolved questions about its structure. One of these puzzles pertains to the anomalous inelastic scattering populating the 4.086-MeV $2_1^+$
level. The measured differential cross-sections for the population of this level in 98-MeV $^{12}$C + $^{208}$Pb and 270-MeV $^{3}$He + $^{208}$Pb inelastic...

I theoretically investigate the spin correlations in two-proton emissions from $^{6}$Be and $^{16}$Ne.
Clauser-Horne-Shimony-Holt (CHSH) inequality is one essential property of quantum-entangled states.
This inequality was introduced by John Clauser et al. for the proof of Bell theorem, which claims that certain consequence of quantum mechanics cannot be reproduced by the...
