We have measured the relative photoionization cross section for the formation of Li{sup 2+} ions between 148 and 161 eV photon energy with higher photon-energy resolution than in previous Li{sup 2+} studies. This energy region is characterized by double and triple excitations that lead to strong enhancements in the Li{sup 2+} cross section. As a result, the double-to-single photoionization ratio shows a dramatic resonance structure not seen before. We have determined the resonance positions and widths using Fano-profile fits to the Li{sup 2+} data and compare them to previously published values and a calculated Li{sup 2+} cross-section curve.
