a-cluster decay from 24Mg resonances produced in the 12C(16O,24Mg)a reaction

A transfer reaction and cluster-decay experiment, C( O, Mg alpha+ Ne)alpha, was performed at a beam 12 16 24 ? 20 energy of 96 MeV. Both recoil and decay alpha particles were detected in coincidence, allowing us to deduce the energy momentum of a Ne fragment. A number of resonant states of Mg were reconstructed up to an excitation energy 20 24 of approximately 30 MeV. Owing to the experimentally achieved excellent resolutions of the Q-value and excitation energy spectra, the relative decay widths for each resonant state in Mg to various final states of Ne were extrac24 20 ted, along with the total decay width. The obtained results provide good testing ground for theoretical descriptions of multiple clustering configurations in 24Mg.

Automated summary

In this experiment, a transfer reaction and cluster-decay were performed to study the resonant states and multiple clustering configurations in 24Mg. The obtained results serve as important validation for theoretical descriptions.
