丰中子核是由能量为215 MeV的离子束入射到薄靶上引发的掠射反应中形成的。结合PRISMA磁谱仪和抑制逃逸Ge探测器阵列，用于探测与射弹状核素一致的靶。基于早期厚靶深非弹性实验结果的符合测量提供了支持布居磷同位素激发态衰减的进一步证据。水平计划的范围内提出和讨论的最先进的壳模型计算。特别是，新的自旋和宇称分配提出了一些激发态的。本文讨论了磷奇同位素低激发态和激发态的能量差随中子数的变化及其与核集体性的关系。还讨论了奇磷同位素第一、第二态和偶磷同位素第一、第三态的壳模型波函数随中子数的演化。
The neutron-rich nucleiwere populated in binary grazing reactions initiated by a beam ofions at 215 MeV incident on a thintarget. The combination of the PRISMA magnetic spectrometer and the CLARA array of escape-suppressed Ge detectors was used to detectrays in coincidence with projectile-like nuclear species. Further evidence to support the observeddecay of excited states of the populated phosphorus isotopes is provided bycoincidence measurements based on the results of an earlier thick-target deep-inelastic experiment. Level schemes forare presented and discussed within the context of state-of-the-art shell-model calculations. In particular, new spin and parity assignments are proposed for a number of excited states of. The evolution with neutron number of the energy difference of the low-lyingandstates in the odd-isotopes of phosphorus, as well as the relationship to nuclear collectivity, is discussed. The evolution with neutron number of the shell-model wave functions of the first, andstates of the odd-phosphorus isotopes and of the first, andstates of the even-isotopes is also explored.
