We have measured the double-to-single photoionization ratio of beryllium (1s{sup 2}2s{sup 2}) between 28 and 40 eV and determined the relative single- and double-photoionization cross sections. In this energy region only simultaneous but not sequential emission of both 2s electrons can take place. We also compare our data with recent theoretical calculations and find good agreement with our data. The previously found scaling law for the double-to-single photoionization ratio is confirmed with high accuracy.
