采用从头算多组态Hartree-Fock方法计算了2p2(3P)3s - 4PJ、2p2(3P) 3P - 4PoJ和2p2(3P) 3P - 4DoJ能级的超精细结构参数。理论的超精细耦合常数与Jennerich等人从近红外无多普勒饱和吸收光谱分析中得出的实验值完全不一致。
Hyperfine structure parameters are calculated for the 2p2(3P)3s 4PJ, 2p2(3P)3p 4PoJ and 2p2(3P)3p 4DoJ levels, using the ab initio multiconfiguration Hartree–Fock method. The theoretical hyperfine coupling constants are in complete disagreement with the experimental values of Jennerich et al deduced from the analysis of the near-infrared Doppler-free saturated absorption spectra.
