摘要:

我们提出了直接测量的超精细分裂的里德堡态在铷87使用电磁感应透明(EIT)光谱在室温蒸气室。用这种方法,尽管多普勒展宽,线宽3.7 MHz FWHM,即显着低于中间状态的自然线宽达到。这使得解决超精细分裂的里德堡s-态n=20. 24.用这种方法,我们能够确定里德伯态超精细分裂的精度约为100 kHz。最终,我们的方法可以达到5 kHz的精度。此外,我们提出了一个直接测量的超精细分辨里德堡态斯塔克位移。这些结果将是非常有价值的未来实验依赖于优秀的知识里德伯态能量和

英文摘要:

We present direct measurements of the hyperfine splitting of Rydberg states in rubidium 87 using Electromagnetically Induced Transparency (EIT) spectroscopy in a room-temperature vapour cell. With this method, and in spite of Doppler-broadening, line-widths of 3.7 MHz FWHM, i.e. significantly below the intermediate state natural linewidth are reached. This allows resolving hyperfine splittings for Rydberg s-states with n=20...24. With this method we are able to determine Rydberg state hyperfine splittings with an accuracy of approximately 100 kHz. Ultimately our method allows accuracies of order 5 kHz to be reached. Furthermore we present a direct measurement of hyperfine-resolved Rydberg state Stark-shifts. These results will be of great value for future experiments relying on excellent knowledge of Rydberg-state energies and
