Two multi-nucleon transfer reactions, 22Ne + 238U and 26Mg + 238U, were used to investigate the structure of light nuclei along the Ne and Mg isotopic chains, approaching the Island of Inversion at N = 20. The experiments were performed at Legnaro National Laboratories using the AGATA-PRISMA setup. A preliminary comparison of excited-state population patterns in 23−25Ne from the two reactions is discussed.

The structure of light nuclei approaching the N = 20 Island of Inversion was investigated in two multi-nucleon transfer experiments performed at Legnaro National Laboratories using the AGATA-PRISMA setup. This paper presents preliminary results on the decay level schemes of23,25Ne. The analysis presented here focuses on the study of negative-parity states to probe the evolution of shell structure along the Z = 10 isotopic chain, and provide stringent constraints for state-of-the-art theoretical models.

2016, a breakthrough anomaly was reported in the isoscalar magnetic dipole transition in ⁸Be via the Internal Pair Creation process. An unexpected angular distribution of the relative angle of the e⁺e⁻ was measured at the Atomki Laboratory. This phenomenon was explained considering the assumption of an emission of a neutral boson, named X17, with a mass of 16.70±0.35(stat)±0.5(syst) MeV/c² and J^π=1⁺. This finding triggered a global campaign to search for the new boson claimed. In Italy, at the Legnaro National Laboratories, a novel scintillator detector array has been designed and built. The present work reports the status of the first in-beam experiments performed in 2023 and 2024.
