本文介绍了一种处理相对论平均场理论中的配对关联的类壳模型方法，它将由此得到的密度迭代回密度。给出了详细的形式和数值方法。作为例子，我们研究了Ne同位素的基态性质和低激发态。由此获得的结果与现有的数据进行了比较。正确地再现了Ne同位素的结合能、奇偶错动以及形状变化的趋势。
A Shell-model-like approach suggested to treat the pairing correlations in relativistic mean field theory is introduced, in which the occupancies thus obtained have been iterated back into the densities. The formalism and numerical techniques are given in detail. As examples, the ground state properties and low-lying excited states for Ne isotopes are studied. The results thus obtained are compared with the data available. The binding energies, the odd–even staggering, as well as the tendency for the change of the shapes in Ne isotopes are correctly reproduced.
