Photoion and photoelectron data for hollow lithium states were recently reported with increased spectral resolution. In order to reproduce and identify the important resonances due to ${2ln}^{\prime }{l}^{\prime }{n}^{″}{l}^{″}$ ${}^2{P}^o$ autoionizing states new photoionization calculations have been performed using the R-matrix code with a 29-term target representation for incident photon energies between 140 and 167 eV. Excellent agreement between theoretical and measured results over partial or total photoionization cross sections confirms the quality of the theoretical model. A determination of the resonance positions for each series converging to a ${2l2l}^{\prime }$ ${}^{1,3}L$ threshold of Li is proposed.
