激发态是在澳大利亚国立大学通过非弹性质子散射以及在肯塔基州大学加速器实验室通过非弹性中子散射填充的。Super-e电子能谱仪和CAESAR康普顿抑制HPGe阵列被用于互补实验，分别测量转换系数和混合比，为一些transitions。所得数据与寿命和分支比相结合，以确定，和状态之间的过渡强度。用内转换电子能谱测量了态间的跃迁强度，并与以前的内电子对形成能谱结果进行了比较。对于所研究的同位素，最低激发态之间的跃迁强度一直很大。
Excited states inwere populated via inelastic proton scattering at the Australian National University as well as via inelastic neutron scattering at the University of Kentucky Accelerator Laboratory. The Super-e electron spectrometer and the CAESAR Compton-suppressed HPGe array were used in complementary experiments to measure conversion coefficients andmixing ratios, respectively, for a number oftransitions. The data obtained were combined with lifetimes and branching ratios to determine, andtransition strengths betweenstates. Thetransition strengths betweenstates were measured using internal conversion electron spectroscopy and compare well to previous results from internal pair formation spectroscopy. Thetransition strengths between the lowest-lyingstates were found to be consistently large for the isotopes studied.
