在入射能量为68MeV的束流中，利用符合快时谱技术测量了keV和keV的同位素态的半衰期，分别为496（23）ps和270（24）ps。提取的W.u.值与该地区的系统学进行比较，并被发现符合单粒子型衰变的typicalstrengths，而不是显示任何证据的additionaldecay阻碍与量子数违反轴向变形系统中观察到的较轻的Ce同位素。
The half-lives of theandyrast states withkeV andkeV in theisotone, have been measured to be 496(23) ps and 270(24) ps, respectively, using the coincident fast-timing spectroscopy technique following population by afusion-evaporation reaction at an incident beam energy of 68 MeV. The extractedW.u. value is compared with the systematics of the region and is found to be in line with typicalstrengths for single-particle-type decays, rather than showing any evidence for the additionaldecay hindrance associated with-quantum number violation in axially deformed systems observed in lighter Ce isotopes.
