| 摘 要： | 本文将红外发散响应理论应用到晶态KCl:OH中OH-的取向变化弛豫过程,研究KCl:OH的低温超声吸收特性。结果表明T>4.5K时,超声吸收的主要贡献来自于热激活弛豫过程;T<4.5K时,超声吸收是热激活弛豫过程和隧道弛豫过程贡献的迭加。

| Abstract: | The infrared divergence response theory is applied to reorientational relaxation process of OH- in KCl: OH to study the behaviour of low temperature ultrasonic absorption in this system. Our calculation results showed that the thermally activated relaxation process makes the main contribution to the ultrasonic absorption for T>4.5K; as for T<4.5K, the tunneling relaxation process can not been neglected. |
