Zakopane 2026 Conference on Nuclear Physics

Several experiments aiming at studying the low energy parts of the Electric Dipole response (the so called Pygmy Dipole Resonance, PDR) in nuclei were carried out during the years and are presently being made. Use of different probes and techniques was made and nuclei in different mass regions were investigated.
The interest in the PDR states is related to their astrophysical implications...

I will present selected results on nuclear giant and pygmy resonances at zero and finite temperatures based on the recent advancements of the nuclear many-body theory [1-6]. The theory will be compactly introduced in a model-independent quantum field theory framework using only the bare fermionic interaction as an input, enabling controllable approximations. A special focus will be placed on...

Finite-temperature effects play a crucial role in shaping exotic nuclear excitations. Thermal unblocking and the weakening of pairing correlations can significantly modify excitation modes of different multipolarities, leading to the emergence of strength that is suppressed at zero temperature. A microscopic description of these effects is therefore important for nuclear structure studies and...

Extreme shape coexistence, of which shape isomers observed in actinide nuclei at spin zero are peculiar examples, is also at the origin of the phenomenon of superdeformation in rapidly rotating nuclei. Nevertheless, the studies of superdeformation have developed virtually in a completely independent manner from other shape-coexistence investigations, mainly because they were carried out almost...

In this invited contribution, I will present recent results from $(d,p)$ experiments performed with the Super-Enge Split-Pole Spectrograph at the John D. Fox Accelerator Laboratory of Florida State University [1] to study single-particle strengths in $fp$-shell nuclei [2-4]. After briefly highlighting the capabilities of the experimental setup [1,5], I will focus on three specific examples....

Collective dynamics in atomic nuclei emerge from the coherent motion of many nucleons and provide important insight into how nuclei respond to external perturbations. Resonant photon scattering, or nuclear resonance fluorescence, provides a clean and selective experimental probe of this response. Since real photons couple directly to nuclear charge and current distributions, they can excite...

Study of photo-nuclear reactions is crucial for understanding nuclear structure and astrophysical processes. The PANDORA (Photo-Absorption of Nuclei and Decay Observation for Reactions in Astrophysics) project [1] aims to systematically investigate these reactions in stable nuclei with mass numbers below 60, both experimentally and theoretically. We use virtual photon exchange through proton...

The discovery of β-delayed neutron emission followed closely that of nuclear fission[1], and the phenomenon was quickly incorporated, into the Bohr-Wheeler compound-nucleus picture[2]. Since that era, β-delayed particle emission has been discussed largely within a two-step statistical framework (the Pandemonium theory [3]).

Over the past decade, several observations have placed this view...

Near-threshold narrow resonances in light nuclei are crucial for nuclear structure studies: they are expected to provide information on the onset of clusterization phenomena, and they also play a key role in nucleosynthesis reactions in stars. A famous example is the Hoyle state in $^{12}$C. In this context, the $\gamma$ decay from near-threshold states, with branches of the order of...

The identification of vibrational dynamics in the low-lying excitation spectra of deformed nuclei continues to be an open challenge in nuclear structure physics. In algebraic, phenomenological, or geometric models, the lowest vibrational shape affecting oscillations that can be built on a deformed ground state include the quadrupole ($\lambda = 2$) and the octupole ($\lambda = 3$) modes....

Isospin symmetry arises from the charge independence of nucleon–nucleon interactions, but it is broken by the Coulomb interaction. Although a small effect, its precise determination is essential for understanding isobaric analogue states and their role in β decay.
In self-conjugate N = Z nuclei, electromagnetic selection rules forbid electric dipole (E1) γ decay. Therefore, the observation of...

The commissioning of a proton cyclotron for hadron therapy at the Cyclotron Centre Bronowice (CCB) of the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Krakow has enabled the use of proton beams for nuclear physics experiments. Among others, an experimental campaign was carried out aiming at study the γ decay from excited atomic states, such as giant and pygmy...

The 4n system 8He, comprising several features of a 2n and 4n sub-system is interesting by its internal correlations leading to the possibility to study several aspects of clustering in light nuclei. 8He, in particular it’s coulomb breakup, studied in a recent experiment, will be presented and discussed. The relation to previously obtained information will be drawn and future prospects arising...

We study the coupling between nuclear shape and rotation in even-even nuclei using a microscopic five-dimensional collective Hamiltonian based on relativistic density functional theory.

First, we identify wobbling motion—a precession of the total angular momentum about the medium axis—in triaxial nuclei such as ruthenium, palladium, and osmium. Using spin coherent state maps, we show that...
