富中子同位素的能级方案是通过中束能量下射弹束破碎后的束内射线光谱研究的。通过与模型空间中的壳模型计算进行比较来补充的重合关系信息被用来构建这些富中子核的激发能级方案。对于奇数质量同位素，提出了一个能级方案，该方案在低能量下看起来基本上是完整的，并且耗尽了 SDPF-MU 壳模型哈密顿量所预测的状态。通过分析过渡矩阵元素和壳模型内计算的矩，提出了简单的尼尔森配置，用于低位激发态。
The level schemes of the neutron-richisotopes are investigated via in-beam-ray spectroscopy following the fragmentation of aprojectile beam at intermediate beam energies. Information oncoincidence relationships complemented by comparisons to shell-model calculations in themodel space were used to construct excitation level schemes for these neutron-rich nuclei. For the odd-massisotopes, a level scheme is presented that appears essentially complete at low energies and exhausts the states predicted by the SDPF-MU shell-model Hamiltonian. Simple Nilsson configurations are proposed for the low-lying excited states offrom an analysis of thetransition matrix elements and moments calculated within the shell model.
