Description

We plan to propose a new experiment at RIBF employing the LISA active target in combination with the DALI2+ $\gamma$-ray spectrometer to investigate the evolution of collectivity from $^{64}$Cr$_{40}$ (center of the island of inversion) to $^{62}$Ti$_{40}$. By combining complementary observables—such as lifetimes, momentum distributions, and reaction cross sections—deduced from one- and two-proton removal reactions, we aim to gain new insights on the low-$Z$ shore of the island of inversion and the predicted shape coexistence.
