一、引言原子核 g 因子的精确程度如何将对核物理起重大作用,当前核物理中,原子核的集体运动模型一般认为是比较完整的模型,并且在当前只有这个模型计算了核的磁矩,从而获得核的g 因子。所以,在实验中测得的 g 因子值与理论上 g 因子值的符合与否,将是检验核模型的一个重要依据。本文通过对穆斯堡尔元素在磁场的作用下产生塞曼效应而出现谱线的磁分裂,即所谓原子核的超精细分裂谱的分析,从特殊情况推到一般情况,用比较有代表性的Fe 14.4KeV 的穆斯堡尔谱为例,来探讨原子核激发态的 g 因子。
I. INTRODUCTION How the exactness of the nuclear g factor plays a significant role in nuclear physics. In the current nuclear physics, the collective motion model of nuclei is generally considered to be a relatively complete model, and only the model has been used to calculate the magnetic moment of the nucleus Obtain nuclear g factor. Therefore, whether the g factor value measured in experiment and the g factor value theoretically match or not will be an important basis for testing the nuclear model. In this paper, we analyze the magnetic splitting of the line due to the Zeeman effect caused by the magnetic field of the Münsburg element, that is, the analysis of the hyperfine splitting spectrum of the so-called atomic nucleus. From the special case to the general case, For example, the Mossbauer spectrum of Fe 14.4KeV is used to investigate the g-factor of the nuclear excited state.
