我们研究了反应。原子核位于和之间，后者是"反转岛"的中心，其特征是低洼的中子壳层构型。结果表明，中子的第二激发态具有较大的壳层占据。该实验是在逆运动学使用HELIcal轨道光谱仪（HELIOS）在阿贡国家实验室。使用SDPF-MU相互作用的壳模型计算得到了能级能量和两个中子转移振幅，这些能量和振幅用于一步扭曲波玻恩近似计算，以提供质子角分布的理论预测。在许多但并非所有情况下，数据与理论预测非常一致。
We have studied thereaction. The nucleuslies betweenand, the latter of which is central to the “island of inversion” characterized by low-lying neutron-shell configurations. The present results show that the second-excitedstate incontains large-shell occupation for the neutrons. The experiment was performed in inverse kinematics using the HELIcal Orbit Spectrometer (HELIOS) at Argonne National Laboratory. Shell-model calculations using the SDPF-MU interaction yielded level energies and two-neutron transfer amplitudes that were used in one-step distorted-wave Born approximation calculations to provide theoretical predictions of the proton angular distributions. In many, but not all cases, the data were in good agreement with theoretical predictions.
