和的中子活化源都有一个同分异构的第一激发态作为子产物。通过对这两种衰变的独立测量，我们测量了壳层和总的内转换系数，对于39.8 keV跃迁，它使该状态去激发，分别为141.1（23）和1428（13）。与Dirac-Fock计算结果相比，我们的新结果与忽略壳层原子空位的理论不一致，这与我们在一系列高空位原子核的高多极跃迁测量中得出的结论一致.包括原子空位的计算表明，跃迁实际上有一个混合比为（5）的小分量。
Neutron-activated sources ofandboth share the isomeric first-excited state inas a daughter product. From independent measurements of both decays, we have measured theshell and total internal-conversion coefficients,and, for the 39.8-keVtransition, which de-excites that state in, to be 141.1(23) and 1428(13), respectively. When compared with Dirac-Fock calculations, our new results disagree with the version of the theory that ignores the-shell atomic vacancy, which is consistent with our conclusion drawn from a series of measurements on high multipolarity transitions in nuclei with higher. Calculations that include the atomic vacancy indicate that the transition actually has a smallcomponent with mixing ratio(5).
