用紫外激光研究了在磁光阱中制备的激发锂-7原子的光谱。里德堡原子能量的激光诊断是基于测量超冷原子的共振荧光强度的变化，当激发的紫外线辐射频率通过里德堡跃迁频率。在主量子数n从38到165的较宽范围内，得到了不同nS构型的能量。讨论了实验所得和理论预测的量子缺陷值和电离能值。
The spectra of excited lithium-7 atoms prepared in a magneto-optical trap are studied using a UV laser. The laser diagnostics of the energy of Rydberg atoms is developed based on measurements of the change in resonance fluorescence intensity of ultracold atoms as the exciting UV radiation frequency passes through the Rydberg transition frequency. The energies of various nS configurations are obtained in a broad range of the principal quantum number n from 38 to 165. The values of the quantum defect and ionization energy obtained in experiments and predicted theoretically are discussed.
