摘要 利用激光冷却与俘获技术获得冷原子,由双光子激发产生超冷里德堡原子,利用场电离法得到了里德堡原子ns和nd态的离子谱图;再将激光波长固定在6p3/2—34d态的共振跃迁线上,得到了离子和里德堡原子的TOF(TimeofFlight)图,并对实验结果做了分析。 The cold,trapped atoms were excited to Rydberg states via two-photon excitation.Using field ionization pulse,the ion spectrum of Rydberg atoms at ns and nd states is detected by scanning the dye laser wavelength.Fixing the dye laser wavelength to resonate with the 34d state,the TOF signals of ion and Rydberg atom are detected.
