论文摘要
转移反应和集群 - 纽约实验,$^{12} $ c($^{16} $ o,$^{24} $ mg $ \ rightArrow $ \ rightArrow $α$+$+$+$+$+$^{20} $ ne)$α$,以96 mev的光束能量进行。偶然检测到后坐力和衰减$α$颗粒,使我们能够推断出$^{20} $ ne碎片的能量。 $^{24} $ mg的许多共振状态被重建至激发能量约为30 meV。由于实验实现了$ Q $值和激发能源光谱的出色分辨率,因此单独提取了$^{24} $ mg每个共振状态的相对衰减宽度,单独提取了$^{24} $ mg的$^{24} $ mg。获得的结果为$^{24} $ mg中多个聚类配置的理论描述提供了良好的测试基础。
A transfer reaction and cluster-decay experiment, $^{12}$C($^{16}$O,$^{24}$Mg$\rightarrow$$α$+$^{20}$Ne)$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 energy-momentum of a $^{20}$Ne fragment. A number of resonant states of $^{24}$Mg were reconstructed up to an excitation energy 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 $^{24}$Mg to various final states of $^{20}$Ne were extracted, alone with the total decay width. The obtained results provide good testing ground for theoretical descriptions of the multiple clustering configurations in $^{24}$Mg.
