反冲标记技术已被用于结合在88 MeV的束能量的反应，以确定与衰变的theand，暂定，在核中的状态的过渡。这些数据被用来，沿着与以前公布的数据，以检查三重态能量差（TED）的质量70等压线。将实验TED值与壳模型计算进行比较，壳模型计算是在模型空间中使用JUN 45相互作用进行的，其中包括具有100 keV等张量强度的Isospin非守恒（INC）相互作用。的协议被发现是非常好的自旋4，并支持模拟状态的期望，所有三个核具有相同的扁圆形状在低自旋。计算结果与实验和壳模型预测的质量为66和74的系统的TED和镜像能量差（MED）进行了比较。的比较清楚地表明，在复制TED数据在该地区的等张量INC相互作用的重要性。与观察到的MED值及其解释壳模型内的问题进行了讨论。
The recoil-tagging technique has been used in conjunction with thereaction at a beam energy of 88 MeV to identify transitions associated with the decay of theand, tentatively,states in the nucleus. These data are used, along with previously published data, to examine the triplet energy differences (TED) for the mass 70 isobars. The experimental TED values are compared with shell model calculations, performed with the JUN45 interaction in themodel space, that include aisospin nonconserving (INC) interaction with an isotensor strength of 100 keV. The agreement is found to be very good up to spin 4 and supports the expectation for analog states that all three nuclei have the same oblate shape at low-spin. Theresults are compared with the experimental and shell model predicted TED and mirror energy differences (MED) for the mass 66 and 74 systems. The comparisons clearly demonstrate the importance of the isotensor INC interaction in replicating the TED data in this region. Issues related to the observed MED values and their interpretation within the shell model are discussed.
