最新的实验数据在132 Sn允许我们第一次确定的自旋轨道分裂的中子和质子在相同的轨道在这个富中子的双幻区，并比较的情况下，208 Pb。使用新的结果，这是现在一致的两个中子丰富的双幻区，理论分析定义的同位素依赖的平均场自旋轨道势，并导致一个简单的显式表达式的中子和质子的自旋轨道分裂之间的差异。同位素的依赖性解释在不同的理论方法的框架。
The latest experimental data on nuclei at132Sn permit us for the first time to determine the spin-orbit splittings of neutrons and protons in identical orbits in this neutron-rich doubly magic region and compare the case to that of208Pb. Using the new results, which are now consistent for the two neutron-rich doubly magic regions, a theoretical analysis defines the isotopic dependence of the mean-field spin-orbit potential and leads to a simple explicit expression for the difference between the spin-orbit splittings of neutrons and protons. The isotopic dependence is explained in the framework of different theoretical approaches.
