摘要:

利用简并二能级方案(DTLS)研究了亚稳惰性气体~(83)Kr ~* 原子亚自然线宽的电磁诱导吸收(EIA)共振.这是首次在亚稳态惰性气体原子中观察到EIA效应。利用这些对应于~(83)Kr ~* 原子从4p ~(55)s [3/2]~ 2到4p ~(55)p [5/2]~ 3超精细闭合跃迁的窄谱EIA信号,我们在外加几高斯的小磁场下,精确地测量了闭合跃迁低能级(F = 13/2)的Lande g因子(gF)。

英文摘要:

We report electromagnetically induced absorption (EIA) resonances of sub-natural linewidth (FWHM) in metastable noble gas 83Kr* atoms using degenerate two level schemes (DTLSs). This is the first observation of EIA effect in a metastable noble gas atoms. Using these spectrally narrow EIA signals obtained corresponding to the closed hyperfine transition from 4p55s[3/2]2 to 4p55p[5/2]3 hyperfine manifolds of 83Kr* atoms, we have measured the Lande's g-factor (gF) for the lower level (F = 13/2) of the closed transition accurately with small applied magnetic fields of few Gauss.
