两对正宇称和负宇称二重带以及连接它们的正宇称带和负宇称带的八个强电偶极跃迁已被确认。它们被解释为具有八极相关的多个手性双重带，这是由微观多维约束协变密度泛函理论和三轴粒子转子模型计算支持的。这一观察报告了八极软核中手征几何的第一个例子。
Two pairs of positive-and negative-parity doublet bands together with eight strong electric dipole transitions linking their yrast positive- and negative-parity bands have been identified in. They are interpreted as multiple chiral doublet bands with octupole correlations, which is supported by the microscopic multidimensionally-constrained covariant density functional theory and triaxial particle rotor model calculations. This observation reports the first example of chiral geometry in octupole soft nuclei.
