AI 中文摘要
原子核的八极形变对核结构和基本对称性的精密检验均具重要意义，但识别八极集体性区域仍具挑战性。我们分析奇质量核的低能谱，发现一种此前未被认识的经验规律，可作为相邻偶偶核中八极集体性的标志。该观测模式可在核心耦合图像中得到解释，与此前理论研究一致，并能对丰中子及缺质子核作出预测。这些发现为识别未来实验和微观计算的有希望候选体提供了简单的经验指南。
英文摘要
Octupole deformation in atomic nuclei is of interest for both nuclear structure and precision tests of fundamental symmetries, but identifying regions of octupole collectivity remains challenging. We analyze low-energy spectra of odd-mass nuclei and uncover a previously unrecognized empirical regularity that serves as a signature of octupole collectivity in neighboring even-even systems. The observed patterns, which can be understood within a core-coupling picture, are consistent with previous theoretical studies and lead to predictions for neutron-rich and proton-deficient nuclei. These findings provide a simple empirical guide for identifying promising candidates for future experiments and microscopic calculations.
