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

Emmanuel CLEMENT ({CNRS}UPR3266)

6/22/23, 9:00 AM

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

Olivier Sorlin (GANIL)

6/22/23, 9:20 AM

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)

6/22/23, 9:40 AM

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)

6/22/23, 10:00 AM

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)

6/22/23, 10:50 AM

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)

6/22/23, 11:10 AM

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...
