51Ar的核结构是迄今为止未知的领域，通过(p,2p)反应，使用γ射线光谱法研究束缚态，使用不变质量法研究非束缚态。在γ射线能谱中检测到2个峰，在50Ar+n相对能谱中观察到6个峰。将结果与我们的壳模型计算结果进行比较，建立了两个束缚态和六个非束缚态。由于与 50 Ar 第一激发态衰变相关的事件的相对能谱中的计数较少，因此只能暂时放置三个未结合态。填充 51 Ar 的两个束缚态的低横截面可以解释为氩同位素中中子数 32 和 34 处存在显着亚壳层闭合的明显特征。研究还表明，由于存在两个价空穴，51Ar中未结合的集体态与个体粒子态共存。
The nuclear structure of51Ar, an uncharted territory so far, was studied by the (p,2p) reaction usingγ-ray spectroscopy for the bound states and the invariant mass method for the unbound states. Two peaks were detected in theγ-ray spectrum and six peaks were observed in the50Ar+n relative energy spectrum. Comparing the results to our shell-model calculations, two bound and six unbound states were established. Three of the unbound states could only be placed tentatively due to the low number of counts in the relative energy spectrum of events associated with the decay through the first excited state of50Ar. The low cross sections populating the two bound states of51Ar could be interpreted as a clear signature for the presence of significant subshell closures at neutron numbers 32 and 34 in argon isotopes. It was also revealed that due to the two valence holes, unbound collective states coexist with individual-particle states in51Ar.
