在使用通过将激光束聚焦在高原子序数的靶上产生的连续谱的技术中，研究了在200至50 A的第二激光产生的等离子体中形成的Li/sup +/的空间分辨吸收光谱。观察到双激发共振1 s/sup 2/ /sub1/S-2snp /sup 1/P以及主系列和相邻的光电离连续谱。从吸收曲线导出2s 2 p/sup 1/P的Fano参数q和Gamma。并与理论进行了比较。
In a technique using a continuum generated by focusing a laser beam on a target of high atomic number, the spatially resolved absorption spectrum of Li/sup +/ formed in a second laser-produced plasma was studied from 200 to 50 A. The doubly excited resonances, 1s/sup 2/ /sub 1/S-2snp /sup 1/P, as well as the principal series and its adjoining photoionization continuum were observed. The Fano parameters, q and GAMMA, of the 2s2p /sup 1/P were derived from the absorption profile. Comparison is made with theory.
