In the past, the Stern–Gerlach experiment has been used as a standard method for analyzing the population of magnetic substates contained in spin-polarized and/or state-selected atomic/molecular beams. However, this experiment is quite demanding due to its low signal intensity and difficulty in beam alignment. The present study shows that the use of a hexapole magnet and a spin flipper, together with the time-of-flight analysis, allows us to conduct an almost equivalent analysis while greatly improving the signal intensity. Applications to the analysis of spin-polarized triplet excited helium and state-selected O₂(${}^3{\mathrm{\Sigma }}_g^{-}$) beams are presented.

六极磁体和自旋鳍片结合飞行时间分析来表征状态选择的顺磁原子/分子束

过去，斯特恩-盖拉赫（Stern-Gerlach）实验已用作分析自旋极化和/或状态选择的原子/分子束中所包含的磁性亚态总体的标准方法。然而，由于其信号强度低和光束对准困难，该实验要求很高。本研究表明，六极磁体和自旋鳍片的使用以及飞行时间分析使我们能够进行几乎等效的分析，同时极大地提高了信号强度。自旋极化三重态激发氦和态选择O ₂（${}^3{\mathrm{\Sigma }}_G^{-}$）光束。
