一种新的实验技术已被开发出来，用于观察自由的、经质量选择的离子的微量光吸收。该技术将线性射频离子阱与高品质光学腔相结合，以进行腔衰荡光谱学（为了通用性也称为光子阱光谱学），其中光子在腔内的存储寿命提供了足够高的灵敏度来探测被捕获的离子。给出了锰离子Mn(+)的吸收光谱，展示了紫外波段(7)P(2,3,4)←(7)S(3)跃迁的超精细结构。螺线管磁铁的应用使我们也能够观察到塞曼分裂和法拉第旋转。
A novel experimental technique has been developed to observe a trace of optical absorption of free mass-selected ions. The technique combines a linear radio-frequency ion trap with a high-finesse optical cavity to perform cavity ring-down spectroscopy (photon-trap spectroscopy for generality), where the storage lifetime of photons in the cavity provides a sensitivity high enough to probe the trapped ions. Absorption spectra of the manganese ion Mn(+) are presented, showing hyperfine structures for the (7)P(2,3,4)<--(7)S(3) transitions in the ultraviolet range. Implementation of a solenoidal magnet allows us to observe the Zeeman splitting and the Faraday rotation as well.
