Away from the valley of stability, the imbalance between the number of protons and neutrons serves as a magnifying lens for specific components of the nuclear interaction that cannot be studied otherwise. In such regions of the nuclear chart, new phenomena as appearance or disappearance of magic numbers, shape coexistence or transitions, are examples of the manifestation of the influence of...

Exotic nuclei, far from stability, are a perfect laboratory to probe the specific components of the nuclear interaction. The imbalance between the number of protons and neutrons can lead to the appearance of phenomena such as sudden shape transitions and shape coexistence. The nuclei with Z and N around 40 and 60, respectively, show one of the most remarkable examples of sudden nuclear shape...

The region of neutron-rich nuclei around $N= 60$ has attracted interest in the late eighties, and even until now, its unique features continue to be of great importance in our understanding of shape evolution far from stability. First indirect evidence of shape coexistence in the region comes from a substantial increase in the two-neutron separation energy together with the difference in...

The search for chargeless nuclei consisting only of neutrons has been a long-lasting challenge in nuclear physics, dating more than six decades back (see Ref. [1] for a recent review). The tetraneutron, in particular, has attracted a lot of experimental and theoretical attention. Most models agree that nuclear forces cannot bind four neutrons together without destroying many of the other...

Light proton-unbound nuclei, $^8$C, $^7$B, $^6$Be and $^5$Li, were investigated by the missing mass method. By using this method, we can measure resonances independently of their decay channels. This is efficient especially for the four-proton unbound nucleus $^8$C. Decay channels can be also investigated by the coincidence detection.

Fission of atomic nuclei is often affected by quantum effects leading to asymmetric mass splits.

HIVER, Corentin (IJCLab)
Fission shape isomers (SI) are poorly understood metastable states characterized by a second superdeformed potential energy minimum co-existing with normal deformed states in the low-spin regime [1]. Although many such isomers have been observed in the actinide region, our understanding of the states in the second minimum remains very limited. For most SIs, the only available information is...

KSHETRIMAYUM, Rojeeta Devi (GANIL)Instrumentation and Technical developmentsPoster presentation
Recent advancements in active target detectors, enabling the detection gas to act as a target for nuclear reactions, have provided a significant boost to the exploration of nuclei near the drip lines and the exotic nuclear phenomena associated with them. ACTAR-TPC at GANIL is a novel detector of such kind that can construct a 3-D mapping of the decay or reaction products from two-dimensional...

The neutron rich region around A ~ 100 is of special interest in nuclear structure for its many rapid shape transitions. Their exact properties are predicted differently by different nuclear structure models, making this region well suited as a testing ground.

SIGALLON, Marie (LSI Polytechnique)
Flexibility and strong polarization of its beta crystalline phase has made the homopolymer PVDF (Polyvinylidene Fluoride) a worldwide studied piezomaterial in the development of piezogenerators and the domain of energy harvesting. The race to achieve the best piezoperformances with this material is on. The actual research trend is focused on developing flexible composite piezomaterials with...

This research is focused on studying nuclear structure in the A ~ 100 region, with a particular emphasis on the N ~ 56 isotone group. The presence of the h11/2 intruder orbital in this group significantly impacts the nuclear shape. The main goal of this study is to investigate the existence of a two-quasi-neutron octupole band within this isotone group.
For this purpose, fusion-evaporation...

M. CHEVALIER, Aurélien (LPC Caen (ENSICAEN-CNRS/IN2P3-UCN))
In reactors, oxygen is present in abundance in the form of water, and/or in the form of oxide in the fuel used (in the case of Pressurised Water Reactors and Fast Reactors). These oxygen nuclei are responsible for 25% of helium formation in nuclear reactors due to the reaction 16O(n,α)13C. However, this reaction still shows significant discrepancies between experimental and evaluated data that...

KUMAR, Neeraj (Grand Accélérateur National d’Ions Lourds (GANIL))
The study of nuclear fission [1] plays a crucial role in understanding the fundamental aspects of nuclear physics and holds significant applications across various fields, including power production, space exploration, and the synthesis of radioisotopes for medical applications. In the ongoing fission campaign at the VAMOS++ facility [2], located at GANIL, we investigate the phenomenon of...

Dr AKTAS, Ozge (GANIL)Poster presentation
The structure of atomic nuclei can be described using the single-particle picture, especially for nuclei with magic numbers such as 8, 20, 28, 50, 82, and 126. In these nuclei, there are significant energy gaps between occupied and valence orbitals. However, in reality, the atomic nucleus is a correlated system where nucleons occupy valence orbits, leading to a diffuse Fermi surface. The N=40...

NUMEN proposes to measure the absolute cross section of Double Charge Exchange reactions in nuclei of interest for the 0νββ decay since the two processes present important similarities even if they are mediated by different interactions. The existing large acceptance spectrometer MAGNEX has been used for pilot runs with $^{20}$Ne and $^{18}$O beams provided from the existing cyclotron at...

The fusion probability for the production of superheavy nuclei (SHN) in cold fusion reactions (1n channel) on $^{208}$Pb and $^{209}$Bi targets drops by approximately five orders of magnitude, from $10^{-1}$ to $10^{-6}$, with the change of projectile atomic number from 20 (Ca) to 30 (Zn). Recent experimental results for reactions induced on $^{20 8}$Pb target by $^{48}$Ca, $^{50}$Ti, and...

Research on neutron-rich nuclei in the heavy and superheavy mass region is gaining importance in the fields as the synthesis of new elements [1,2,3], the r-process and multi-nucleon transfer reactions. Furthermore, the use of neutron-rich nuclei is indispensable for reaching the Island of Stability [4] that are predicted to exist in the superheavy element region, and the evaluation of the...
