Nature and decay of a Jπ=36+ resonance in the 24Mg + 24Mg reaction

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