Masses of neutron-rich, odd-odd Pm, Eu and Tb nuclei near N=98 were measured using the Canadian Penning Trap mass spectrometer at the Californium Rare Isotope Breeder Upgrade (CARIBU) facility. High-resolution mass measurements yielded the discovery of spin-trap isomers at N=97 in 162Tb, and in the N=99 isotones of 160Pm and 164Tb. Furthermore, no evidence of long-lived isomers were observed at N=95 in 158Eu, at N=97 in 158Pm, nor at N=101 in 164Eu and 166Tb. These experimental observations are compared with results from multi-quasiparticle blocking calculations.

富中子,奇数Pm,Eu和Tb原子核的质量 ñ=98在Californium Rare Isotope Breeder Upgrade(CARIBU)设施中使用加拿大潘宁阱质谱仪进行了测量。高分辨率质量测量产生了自旋陷阱异构体的发现ñ=97162Tb,并在 ñ=99 的同调 160Pm和 164待定 此外,没有观察到长寿命异构体的证据。ñ=95158欧盟,在 ñ=97158下午,也不在 ñ=101164欧盟和 166待定 将这些实验观察结果与多准粒子阻塞计算的结果进行比较。
