| 摘 要： | 本文给出了计算多声子跃迁中电声子耦合最小S因子的公式,它具有不依赖晶格振动具体模式的优点,在此基础上具体估算了LaF3晶体中Ho3+稀土杂质在 5F1,5F4,5F5,5G4,5G5能级之间的多声子跃迁的S因子,得到S为0.05左右,这是与通常的实验结果相符的。

| Abstract: | A formula is given for calculating minimum electron-phonon coupling S factor in mul-tiphonon transitions, this formula has the advantage of being independent of lattice vibration modes. The S factors have been evaluated for the multiphonon transitions among the multiplets 5F1,5F4,5F5,5G4,5G5 of Ho3+ ion in the LaF3 crystal. The values obtained for the S factor are around 0.05, which is in agreement with experimental results. |
