采用反冲距离多普勒频移（RDDS）技术同时测量了两种等压类似物的寿命。在靶上有光束的聚变-蒸发反应中填充状态。本文利用现有的等压模拟态数据，对三个等压核的同位旋对称性进行了分析和计算。壳模型计算再现了数据随增加的幅度和增加趋势。为了得出关于三重态中同位旋混合水平的确切结论，将需要对跃迁速率进行新的精确测量。
Lifetimes of theisobaric analogstates inandwere measured simultaneously by employing the recoil distance Doppler-shift (RDDS) technique. The states were populated in a fusion-evaporation reaction with abeam on atarget. An analysis of the data and the calculations from the present work, together with the availabledata of the isobaric analog states inand, were used to study isospin symmetry in the threeisobaric nuclei. Shell-model calculations reproduce the magnitudes as well as the increasing trend of thedata with increasing. To draw a firm conclusion on the level of isospin mixing in the triplet, a new precision measurement of thetransition rate inwill be required.
