Abstract: 
Absolute cross-section measurements for resonant double photoexcitation of Li+ ions followed by autoionization have been performed at high resolution in the photon energy range from 148 eV, just below the (2s2p, (2)(0, 1)(n)(+)) resonance, to 198 eV (the region of the double ionization threshold). The measurements have been made using the photon-ion merged-beam endstation at the Advanced Light Source, Lawrence Berkeley National Laboratory, USA. The absolute cross-section measurements show excellent agreement with theoretical results from the R-matrix plus pseudo-state (RMPS) method. Comparisons between theory and experiment for the Auger resonance energies, autoionization linewidth (Gamma) and the Fano line profile index q for several members of the principal (2snp, (2)(0, 1)(n)(+)) and (3snp, (3)(1, 1)(n)(+)) Rydberg series found in the photoionization spectra for the P-1 degrees symmetry show satisfactory accord.
