摘要：

We have investigated the relative triple-photoionization cross section of lithium from near threshold to 650 eV photon energy using monochromatized synchrotron radiation. Specifically, we reduced the statistical error bars in the 300 to 420 eV region and significantly extended the energy range compared to previous measurements. From the measured triple-to-double photoionization ratio, we determine the triple-to-single photoionization ratio and derive the triple-photoionization cross section. We make an estimate for the high-energy limit of that ratio and compare it to theoretical predictions. We also compare the Li3+ cross section with theoretical calculations.
