摘　　要：采用矩阵对角化方法计算了(40)^Ca^(35)Cl分子的超精细结构能级,借助有效哈密顿算符获得了(40)^Ca^(35)Cl分子基态超精细能级的本征值.计算结果表明,得到的跃迁光谱数据与实验值符合的很好,误差仅在0 k Hz~90 k Hz,并好于之前的理论计算值.希望这些数据能为以后激光冷却(40)^Ca^(35)Cl分子提供有力的理论依据.The hyperfine structure energy levels of (40)^Ca^(35)Cl molecules are calculated by matrix diagonalization method. The calculation results show that the obtained transition spectrum data are in good agreement with the experimental values,and the error are only 0 k Hz to 90 k Hz,which is better than the previous theoretical calculation. It is hoped that these data can provide a useful theoretical basis for laser-cooled (40)^Ca^(35)Cl molecule in the future.
