摘要:

本文讨论了利用均匀恒定磁场区域实现H(2S)光束的双态原子偏振器。我们已经观察到,具有这样的场配置的设备能够在宽范围的磁场强度和原子速度下实现有效的极化。此外,我们建立了一个标准,必须满足确认成功的极化。这是可能的,因为对于出射的两态原子束,莱曼- $α$辐射具有特定的拍频模式。

英文摘要:

We discuss the use of a region of uniform and constant magnetic field in order to implement a two-state atomic polarizer for an H(2S) beam. We have observed that a device with such field configuration is capable of achieving an efficient polarization for a wide range of magnetic field intensities and atomic velocities. In addition, we establish a criterion that must be met to confirm a successful polarization. That is possible due to a specific beating pattern for the Lyman-$α$ radiation expected for the outgoing two-state atomic beam.
