| 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.

| Abstract: | The hyperfine structure energy levels of 40Ca35Cl molecules are calculated by matrix diagonalization method. The calculation results show that the obtained transition spectrum data is in good agreement with the experimental values, and the error is only 0 kHz to 90 kHz, which is better than the previous theoretical calculation. It is hoped that these data can provide a useful theoretical basis for laser-cooled 40Ca35Cl molecule in the future. |
