Abstract

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 of \ (^23, 25\) Ne. 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.
