Binary reaction decays from ²⁴Mg+¹²C

Charged-particle and γ decays in ²⁴Mg^∗ are investigated for excitation energies where quasimolecular resonances appear in ¹²C + ¹²C collisions. Various theoretical predictions for the occurrence of superdeformed and hyperdeformed bands associated with resonance structures with low spin are discussed within the measured ²⁴Mg^∗ excitation energy region. The inverse kinematics reaction ²⁴Mg + ¹²C is studied at E_lab(²⁴Mg) = 130 MeV, an energy that enables the population of ²⁴Mg states decaying into ¹²C + ¹²C resonant breakup states. Exclusive data were collected with the Binary Reaction Spectrometer in coincidence with Euroball IV installed at the Vivitron tandem facility at Strasbourg. Specific structures with large deformation were selectively populated in binary reactions, and their associated γ decays studied. Coincident events associated with inelastic and α -transfer channels have been selected by choosing the excitation energy or the entry point via the two-body Q values. The analysis of the binary reaction channels is presented with a particular emphasis on ²⁴Mg − γ, ²⁰Ne − γ, and ¹⁶O - γ coincidences. New information (spin and branching ratios) is deduced on high-energy states in ²⁴Mg and ¹⁶O , respectively.
