在能量为96MeV的束流上进行了C（O，Mg α+ Ne）α的转移反应和团簇衰变实验。反冲和衰变α粒子都被同时探测到，这使我们能够推断出Ne碎片的能量和动量。镁的共振态的数量进行重建高达约30兆电子伏的激发能量。由于实验上获得了很好的Q值和激发能谱的分辨率，我们提取了Mg中每个共振态与Ne的不同终态的相对衰减宽度，沿着总衰减宽度。所得结果为镁中多重团簇构型的理论描述提供了良好的实验基础。
A transfer reaction and cluster-decay experiment, C (O, Mg α+ Ne) α, was performed at a beam energy of 96 MeV. Both recoil and decay α particles were detected in coincidence, allowing us to deduce the energymomentum of a Ne fragment. A number of resonant states of Mg were reconstructed up to an excitation energy of approximately 30 MeV. Owing to the experimentally achieved excellent resolutions of the Q-value and excitationenergy spectra, the relative decay widths for each resonant state in Mg to various final states of Ne were extracted, along with the total decay width. The obtained results provide good testing ground for theoretical descriptions of multiple clustering configurations in Mg.
