40. Synthesis of Heavy and Superheavy Neutron-Rich Nuclei in Multinucleon Transfer Reactions at Grazing Angle Using Uranium Beams

Mrs barbara Sulignano (CEA Saclay)

10/07/2025, 15:40

Information on the heaviest elements has been obtained up to now via fusion evaporation reactions. It is however well known that the only nuclei one can reach using fusion-evaporation reactions are neutron deficient and moreover in a very limited number due to the restricted number of beam-target combinations. An alternative to fusion-evaporation could be deep-inelastic collisions. Theoretical...

19. Production yields of neutron-rich heavy nuclei in the 238U+124Sn multinucleon transfer reaction

Lorenzo Corradi (Istituto Nazionale di Fisica Nucleare)

10/07/2025, 16:00

In this experiment we intend to measure the 238U+124Sn multinucleon transfer reaction by using the PRISMA + NOSE + AGATAset-up to study the details of the A, Z, Q-value distributions and associated gamma rays. In addition, we will employ a high resolution kinematic coincidence to extract the light-heavy mass-mass correlation and the transfer induced fission probability of the heavy partner. By...

25. Pushing the limits of γ-ray spectroscopy of neutron-rich fission fragments with AGATA–PRISMA coupling

Jérémie Dudouet (IP2I)

In this Letter of Intent, we aim to study the structure of neutron-rich nuclei in the region of 78Ni. The main focus is to investigate states resulting from the coupling between excited states of the inert core and valence protons in the N=50 nuclei 79Cu and 80Zn. In addition, the proposed experiment will provide a systematic and relevant dataset on excited states in this region of the nuclear...

22. Multiple Shape Coexistence in 78Se

Nirupama Sensharma

10/07/2025, 17:00

Through this letter of intent, we propose to investigate the electromagnetic properties of the low-lying states in $^{78}$Se, which is a promising candidate for the observation of multiple shape coexistence. This measurement will be done via a multi-step Coulomb excitation measurement with AGATA in conjunction with the particle detectors SPIDER and DANTE. The primary objective is to measure,...

34. Multiple-shape coexistence in $^{120}$Sn

Tongan Wu

10/07/2025, 17:20

We propose to investigate the phenomenon of multiple-shape coexistence in the $Z\approx50$ region by performing a multi-step Coulomb-excitation measurement of $^{120}$Sn using the AGATA+SPIDER setup.
The aim of the experiment is the measurement of the electromagnetic properties of the low-lying states in $^{120}$Sn, in particular the spectroscopic quadrupole moments of the $2_{1,2,3}^+$...

33. Investigation of the rotational band in $^{120}$Sn

Tongan Wu

10/07/2025, 17:40

We propose to search for the intruder band that builds on the deformed excited $0^+$ states in $^{120}$Sn using fusion-evaporation. While our recent $(n,\gamma)$ measurement showed that the low-lying excited $0^+_{2,3}$ states in $^{120}$Sn are deformed, the expected rotational band which builds on the deformed $0^+$ states have not yet been observed. The aim of this complementary...

29. Electric Dipole Transitions in mirror nuclei

Francesco Recchia (Istituto Nazionale di Fisica Nucleare)

10/07/2025, 18:00

The mirror nuclei with mass 19 offer a unique opportunity to address such study on the violation of isospin symmetry because it is the only case where a 1/2- to 1/2+, having a pure E1 transition. This is a unique opportunity of testing isospin mixing with high precision because in this case mixing with E2 transition is not possible. Only one measurement was performed of this E1 transition. We...
