Spin-polarized hydrogen (SPH) atoms have traditionally been produced and detected using complex experimental methods with poor time resolution. Recently, SPH has been produced by pulsed-laser photodissociation of HCl using circularly polarized light. In combination with the proposed detection of SPH via polarized fluorescence, this approach should allow the production and spatially resolved detection of SPH with a higher sensitivity than that currently available, and with a time resolution in the nanosecond regime. This represents an improvement of several orders of magnitude over the existing methods.
传统上，自旋极化氢（SPH）原子是通过时间分辨率较差的复杂实验方法产生和检测的。最近，利用圆偏振光对HCl进行脉冲激光光解离产生了SPH。结合所提出的通过偏振荧光检测SPH的方法，这种方法应该能够以比目前更高的灵敏度产生和进行空间分辨检测SPH，并且时间分辨率处于纳秒范围。这比现有方法提高了几个数量级。
