在评估双闭亚壳核的无中微子双衰变（）的半衰期时，原子核的结构至关重要。首次研究了聚类方面。通过研究高能区的核彩虹和低能区极端后角激发函数的特征结构，在双折叠模型中很好地确定了粒子与原子核之间的相互作用势。通过研究邻近原子核的散射，双折叠模型的有效性得到了加强。双折叠模型计算很好地再现了在各种入射能量和特征激发函数上观察到的所有角分布。通过使用所获得的势，本着统一描述散射和结构的精神来研究团簇结构。证明了具有簇结构的第二高节点带态的存在，其中与地带相比，在相对运动中多了两个节点被激发。计算很好地再现了与实验相符的地带状态。地频带内过渡的实验值也得到了很好的再现。讨论了聚集对双衰变半衰期的影响。
In the evaluation of the half-life of the neutrinoless double-decay () of a doubly closed-subshell nucleus, the structure of the nucleusis essentially important. The-clustering aspects ofare investigated for the first time. By studying the nuclear rainbows inscattering fromat high energies and the characteristic structure of the excitation functions at the extreme backward angle at the low-energy region, the interaction potential between theparticle and thenucleus is determined well in the double folding model. The validity of the double folding model was reinforced by studyingscattering from neighboring nuclei, and. The double-folding-model calculations reproduced well all the observed angular distributions over a wide range of incident energies and the characteristic excitation functions. By using the obtained potential thecluster structure ofis investigated in the spirit of a unified description of scattering and structure. The existence of the second-higher nodal band states with thecluster structure, in which two more nodes are excited in the relative motion compared with the ground band, is demonstrated. The calculation reproduces well the ground-band states ofin agreement with experiment. The experimentalvalue of the transition in the ground band is also reproduced well. The effect ofclustering inon the the half-life of thedouble-decay ofis discussed.
