摘要: 核子配对近似模型是研究原子核性质的重要方法之一，该方法已经在许多核领域内取得了重要成果。在对核¹²⁹Sn的研究过程中，添加非集体对参数，并将该参数进行调整，从而观察非集体配对方式对核子能态的影响。经过计算后，发现非集体对主要对负宇称能态有较大影响，而在正宇称能态中对角动量较高的能态有较大的影响。

Abstract: The nucleon pair approximation shell model is one of the most important methods for studying the properties of atomic nuclei, and the method has yielded important results in many nuclear fields. During the study of nuclear ¹²⁹Sn, the non-collective pairing parameter is added and the parameter is tuned so as to observe the effect of the non-collective pairing approach on the energy states of nuclei. After calculations, it is found that the non-collective pairing has a large effect mainly on the negative-universal energy states, while in the positive-universal energy states it has a large effect on the energy states with higher angular momentum.
