用Isolde螺线管谱仪通过逆运动学中的相互作用测量，研究了单粒子的性质。来自这些壳层的负宇称入侵态已经被识别出来，并被用于现代壳模型计算的基准。沿同位素的单粒子质心的系统数据表明，在描述观测到的从稳定到稳定的趋势方面，与壳模型的预测很好地一致。然而，也有证据表明，核势的有限几何形状的影响正在对粒子发射阈值附近的理论轨道的行为起作用。
The single-particle properties ofhave been investigated via a measurement of thereaction, in inverse kinematics, using the ISOLDE Solenoidal Spectrometer. The negative-parity intruder states from theshell have been identified and used to benchmark modern shell-model calculations. The systematic data on the single-particle centroids along theisotones show good agreement with shell-model predictions in describing the observed trends from stability toward. However, there is also evidence that the effect of the finite geometry of the nuclear potential is playing a role on the behavior of theorbitals near the particle-emission threshold.
