Abstract : The narrow $\Gamma$=170 keV and high spin $J^{\pi}=36^+$ resonance in the $^{24}$Mg + $^{24}$Mg reaction at E${CM}$= 45.7 MeV has been associated with a hyperdeformed molecular state in $^{48}$Cr. Such a description has important consequences for the resonance decay into the favored inelastic channels. Through fragment- $\gamma$ coincidence measurements performed ON and OFF resonance using the PRISMA-CLARA array, we have identified the $^{24}$Mg states selectively populated: the $2^+$ and $4^+$ members of the ground state band.
