铥空心阴极灯 双色双光子级联共振 超精细结构 Tm hollow cathode discharge lamp series resonance of two color hyperfine structure
摘要
用铥空心阴极灯,采用光电流光谱技术测得铥原子21条一级跃迁谱线,确定了相应跃迁上能级的超精细结构常数,其中7个能级的参数为首次发表,运用同一空心阴极灯,采用双色双光子级联共振技术,由荧光法首次测得4个第二激发能级的超精细结构常数.
Abstract
With a Tm-Kr hollow cathode discharge (HCD) lamp, we measured 21 transition lines of 169TmI by optogalvanic spectroscopy and determined the hyperfine structure constants of the upper levels, among them, seven are firstly reported to our knowledge. With the same HCD, the hyperfine structure constants of four excited levels are measured. by two-color resonance.
