| 摘 要： | 我们在自制的La-Kr阴极灯中,用内调制、消多普勒荧光法研究了镧原子一些能级的超精细结构.据我们所知,其中20197.34cm~(-1)、21447.86cm~(-1)能级的超精细结构常数A、B尚无报道,这还是第一次.此外,还获得了线宽小于40MHz的线型和来自公共低能级的所有交岔线(Cross-Over line).对阴极灯中原子光谱特性进行了研究.

| Abstract: | We used Doppler-free intermodulated fluorescence technique to study the hyperfine sturcture of some levels of La I in a home made La-Kr cathode discharge. The A and B constants for the levels 20197.34cm, 21447.86cm are reported for the first time. We observed a homogenous linewidth of less than 40MHz and all crossover lines between transitions with common lower levels. The spectral characteristics of a cathode discharge are investigated. |
