The $^{24]$Mg + $^{24}$Mg reaction has been studied at the Legnaro Tandem at a CM bombarding energy of 45.7 MeV where a narrow and high spin resonance has been reported previously. The decay of the resonance into the inelastic and fusion-evaporation channels has been investigated. The ON and OFF resonance decay yields have been measured using, for the inelastic channels, the fragment spectrometer PRISMA and the $\gamma$ array CLARA, and, for the fusion-evaporation channels, the Si array EUCLIDES and the $\gamma$ array GASP. The resonant effects observed in both experiments are discussed and it is suggested that the resonance populates a deformed $^{48}$Cr after a Jacobi shape transition.
