一个被捕获的Hg+ 198离子被散射的激光辐射冷却，该辐射被调谐到窄的S 1 2 2− D 5 2 2跃迁的解析的运动下边带。冷却后的上、下边带上的不同吸收强度表明，离子在大约95%的时间处于其限制阱的基态。
A single trapped Hg+ 198 ion was cooled by scattering laser radiation that was tuned to the resolved lower motional sideband of the narrow S 1 2 2− D 5 2 2 transition. The different absorption strengths on the upper and lower sidebands after cooling indicated that the ion was in the ground state of its confining well approximately 95% of the time.
