| 摘 要： | 用全相对论量子力学计算H2O和HLi的双光子偶极激发。为对比起见,同时用非相对论的对称匹配团族-组态相互作用法(SAC-CI)计算其单光子激发。对于无对称中心的H2O和HLi,符合相应群的对称选择原则。双光子跃迁几率一般比单光子跃迁的小3～5个数量级。在计算双光子偶极激发时,应采用同时包含了空间的对称性和时间反转对称性的全相对论。 |

| Abstract: | The two-photon excitation is studied by the full relativistic theory of H2O and HLi. The single-photon excitation of H2O and HLi molecules is also studied using symmetry adapted cluster/configuration interaction (SAC-CI) method for comparison. The excitation probability of two-photon excitation is 3~5 orders of magnitude less than that of single-photon excitation. It is better to use the full relativistic theory, which involves both space and time symmetry, for the calculation of two-photon excitation. |
