提出了一种利用自旋锁定技术实现不同原子间横向磁矩碰撞转移的有效方法。在85 Rb- 133 Cs蒸气上进行了旋转或振荡射频场的演示实验，当射频场的振幅H1与静磁场强度H 0相当时，观察到大量横向磁矩的转移。的H 1 -依赖性的转移，在振荡的射频场的情况下，是不简单的，因为布洛赫Siegert位移和相关的共振效应。用Bloch方程数值分析了85 Rb和133 Cs自旋交换碰撞耦合的横向磁矩在强射频场作用下的转移。
We propose an efficient method of collisional transfer of transverse magnetic moment between different kinds of atoms using the spin-locking technique. Demonstrating experiments with a rotating or an oscillating rf field are carried out on a 85 Rb– 133 Cs vapor, and the transfer of a large amount of the transverse magnetic moment is observed when the amplitude H 1 of the rf field is comparable to the static magnetic field strength H 0 . The H 1 -dependence of the transfer, in the case of the oscillating rf field, is not simple, because of the Bloch-Siegert shift and associated resonance effects. The transfer of the transverse magnetic moment under the strong rf field is numerically analyzed with the Bloch equations for 85 Rb and 133 Cs coupled through spin-exchange collisions.
