Decay of a Jπ=36+ Resonance in the 24Mg + 24Mg Reaction

The narrow (Γ=170 keV) and high spin (Jπ=36+) resonance in the 24Mg + 24Mg reaction at ECM= 45.7 MeV has been associated with a hyperdeformed molecular state in 48Cr. Such a description has important consequences for the resonance decay into the favored inelastic channels. Through fragment‐γ coincidence measurements performed ON and OFF resonance using the PRISMA‐CLARA array, we have identified the 24Mg states selectively populated: the 2+ and 4+ members of the ground state band.
