The double-to-single photoionization ratio of atomic lithium has been measured for photon energies ranging from 120 eV to 910 eV. Through extensive use of various filters we were able to significantly extend the previous range of measurements [M.-T. Huang et al., Phys. Rev. A 59, 3397 (1999)]. We find that our data are in agreement with the predicted high-energy limit of 3.4%. By applying simple model curves to our data, we believe that sequential processes contribute substantially to the double-photoionization cross-section ratio as predicted by theory.
