1. Spectroscopy with AGATA and GRIT at SPES using the 131mSn beam

Emmanuel CLEMENT ({CNRS}UPR3266)

We propose to investigate the 132,131Sn structure using the 131Sn(d,p)132Sn reaction using the GRIT-AGATA setup at 0° degree and the SPES beam. As doubly magic nucleus, 132Sn is a real challange for coulomb excitation and in particular to populate the non-yrast states. The (d,p) reaction is an ideal tool to populate selectively non-yrast state and highlighting new structures. The goals of the...

27. Detailed spectroscopic studies around 132Sn at Legnaro

The strong nuclear force binds the nucleons inside the nucleus and drives the emergence of nuclear structure properties. A rare fraction of nuclei, coined as ``magic", exhibit enhanced stability and play a crucial role in nuclear sciences and related fields. This enhanced stability can be related, within an approximate mean-field description, to the existence of a large energy gap between...

3. Fission fragments spectroscopy at LNL with AGATA-PRISMA: Insights into the magicity of 78Ni.

Jérémie Dudouet (IP2I)

The development of a new $^{238}$U beam at LNL opens up new possibilities to study the structure of the yrast excited states of neutron-rich nuclei in the vicinity of $^{78}$Ni. The focus is to study the states resulting from the coupling of the inert-core excited states and the valence protons in N = 50 isotones of 82Ge, 81Ga and 80Zn.

Already widely studied during the AGATA-VAMOS campaign...

28. Microscopic structure of Pygmy Dipole Resonances in neutron-rich nuclei using transfer reactions

Didier Beaumel (IPN Orsay)

22/06/2023 10:00

Pygmy Dipole Resonances (PDR) are often referred as belonging to the new phenomenology specific of nuclei far from stability. PDR can be seen as new dynamical modes in neutron-rich nuclei associated with the excess neutrons. In most theoretical calculations, the dipole response of neutron-rich nuclei exhibits a small component at energies lower than the standard giant dipole resonance (GDR),...

25. Coexistence de formes A~100

Emmanuel CLEMENT ({CNRS}UPR3266)

22/06/2023 10:50

La coexistence de formes dans les fragments de fission avec A~100 est l'un des phénomènes les plus spectaculaire en physique nucléaire. La transition abrupte entre des noyaux quasi sphérique vers des noyaux très déformées lors du passage de la ligne N=60 pour les Zr et Sr est unique dans la charte des noyaux. Bien que des progrès remarquables ont été obtenu récemment avec les machines ISOL...

4. Probing pairing effects @LNL-SPES

Marlene Assie (IJCLab)

The subject of this LoI is two-fold: first to investigate neutron-neutron pairing effects in the neutron-rich Sn isotopes and second, to investigate the mixed neutron-proton pairing in the heavy nuclei.
Firstly, neutron-proton mixing pairing is predicted to occur in heavy nuclei close to the N=Z line but with an isospin imbalance and within the proton drip-line. Possible experimental...
