摘要：采用SIC-Xα方法,计算了Na原子3p2P3/2态的磁性超精细相互作用耦合系数A,理论计算与实验结果符合得较好。对于电超精细结构,通过理论计算给出电场梯度值q,再由电性超精细相互作用常数B的实验值,得出原子核的电四极矩Q,由此计算出Na原子核的大致结构。这是用原子物理的方法研究原子核问题的有益尝试。
The SIC-Xo method is used to obtain the magnetic dipole hyperfine structure constant A of 3p^2P3/2 state in Na atom. The results agree well with the experiments. For the research of electric hyperfine structure, we calculated the electric field gradient q, and deduced the nuclear electric quadrupole moment Q according to the experimental value of the electric hyperfine coupling constant B. Thus, the structure of Na nucleus is calculated. This is an attempt to reveal the nucleus structure by the method of atomic physics.
