Abstract

The nuclear electric quadrupole moment (QM) is one of the most important bulk properties of the nucleus with which nuclear deformations can be investigated. In this paper the electric quadrupole moment for 6Li nucleus in the ground state is calculated from the hyperfine structure of atomic spectra. Initially a cluster model wavefunction is constructed in shell model using Resonating Group Method (RGM), Generate coordinate method (GCM) and Complex Generator Coordinate Technique (CGCT). CGCT transforms the cluster model wavefunction into antisymmetrized product of single particle wavefunction. The wavefunction is written with the total angular momentum, relative motion between alpha and deuteron clusters, definite parity and spin. The calculations have been made by taking Wood- Saxon potential. The results obtained are compared and found reasonably well in agreement with the experimental results.
利用原子光谱的超精细结构研究6Li原子核的核电四极矩
核电四极矩(QM)是研究核变形最重要的体积性质之一。本文从原子光谱的超精细结构出发,计算了6Li原子核在基态的电四极矩。首先利用共振群法(RGM)、生成坐标法(GCM)和复生成坐标技术(CGCT)在壳模型中构造了聚类模型波函数。CGCT将聚类模型波函数转化为单粒子波函数的不对称积。波函数用总角动量、α和氘核团之间的相对运动、确定宇称和自旋来表示。计算是采用伍德-撒克逊势进行的。对所得结果进行了比较,发现与实验结果相当吻合。
