We report the measurement of the spin polarization of hydrogen (SPH) atoms by (2+1) laser-induced fluorescence, produced via the photodissociation of thermal HBr molecules with circularly polarized 193 nm light. This scheme, which involves two-photon laser excitation at 205 nm and fluorescence at 656 nm, offers an experimentally simpler polarization-detection method than the previously reported vacuum ultraviolet detection scheme, allowing the detection of SPH atoms to be performed more straightforwardly, from the photodissociation of a wide range of molecules and from a variety of collision experiments.
我们报告了通过（2+1）激光诱导荧光测量氢（SPH）原子的自旋极化，该荧光是通过用圆偏振 193nm 光光解热 HBr 分子产生的。这种方案涉及在 205nm 处的双光子激光激发和在 656nm 处的荧光，与以前报道的真空紫外检测方案相比，提供了一种更简单的实验极化检测方法，允许更直接地从广泛的分子光解和各种碰撞实验中检测 SPH 原子。
