12C+12C cluster resonances in 24Mg up to Ex = 50 MeV

The population and decay of excited states in 24Mg have been investigated using the 12C(16O, 12C12C)alpha reaction at beam energies of 135 and 160 MeV . This measurement permitted the decay spectrum to be measured up to 24Mg excitation energies of 70 MeV . Resonance structures were observed up to an excitation energy of 49.4 MeV and spin J = 18[h-bar] . The results are discussed in terms of the termination of a deformed 12C+12C cluster band.
