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+ formed in a second laser-produced plasma was studied from 200 to 50 Å. The doubly excited resonances, 1s21S-2snp1P, as well as the principal series and its adjoining photoionization continuum were observed. The Fano parameters, q and Γ, of the 2s2p1P were derived from the absorption profile. Comparison is made with theory.
