在日本理化学研究所的RIBF装置上，利用裂变态的延迟射线谱研究了丰中子核。这些核是由345束射弹裂变产生的，并由EURICA团簇Ge阵列探测到延迟射线。同分异构态的半衰期分别为339（20）ns和1.63（21）ns。根据Nd同位素的衰变和能级系统学，建立了这些核的第一能级方案。的同质异能态分别被赋予和的自旋，并分别具有和的构型。
The neutron-rich nucleihave been studied via delayed-ray spectroscopy ofisomeric states at the RIBF facility, RIKEN. These nuclei were produced following the projectile fission of a 345beam and delayedrays were detected by the EURICA cluster Ge array. The isomeric states have measured half-lives of 339(20) ns and 1.63(21)forand, respectively. From the observeddecays and the systematics of levels in the neighboring Nd isotopes first level schemes were constructed for these nuclei. The isomeric states ofhave been assigned spins ofand, with proposedandconfigurations, respectively.
