在加利福尼亚州稀有同位素增殖器升级（CARIBU）设施中，使用加拿大Penning阱质谱仪测量了富中子、奇奇Pm、Eu和Tb核的质量。高分辨率的质量测量结果发现了自旋陷阱异构体锡，并在同位素和。此外，没有证据表明存在长寿命的异构体锡，锡，也没有atinand。这些实验观测结果进行了比较，从multiquasiparticle阻塞计算。
Masses of neutron-rich, odd-odd Pm, Eu, and Tb nuclei nearwere 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 atin, and in theisotones ofand. Furthermore, no evidence of long-lived isomers were observed atin, atin, nor atinand. These experimental observations are compared to results from multiquasiparticle blocking calculations.
