Description
We propose a new experiment at LNL using the AGATA+PRISMA setup to investigate the structure of neutron-rich magnesium isotopes near the N=20 Island of Inversion. Using a $^{30}\mathrm{Si}$ beam on a $^{238}\mathrm{U}$ target, we aim to populate $^{30}\mathrm{Mg}$ and neighboring nuclei via multinucleon transfer reactions and measure level lifetimes using the Doppler Shift Attenuation Method (DSAM). The experiment focuses on the evolution of intruder configurations and configuration mixing in even-even and odd-A systems, particularly probing the nature of the $2_2^+$ state in $^{30}\mathrm{Mg}$ and negative-parity states in $^{29}\mathrm{Mg}$. Lifetimes, transition strengths, and spectroscopic information will provide key constraints on shell-model and ab initio calculations, and clarify the onset of collectivity and shape coexistence in this critical region. The results will contribute to a more systematic understanding of structure evolution across isotopic chains approaching the Island of Inversion.
