Abstract :
We report on new experimental data which reveal high spin resonances in 12C+12C scattering. We have measured excitation functions for the 12C [12C, 12C(31−) + 12C(31−)] reaction over the centre of mass energy range Ec.m.=31 to 45 MeV. Resonances have been observed at Ec.m.=32.5, 37.5 and 43 MeV. Detailed angular correlation measurements have been performed at the energy corresponding to the peak of each resonance. From an analysis of the angular correlations we suggest a dominant angular momentum of J=22 at the highest energy. We interpret the results in terms of an α cluster model of superdeformed states in 24Mg.
