%X The photolysis of the hydronium cation H3O+ has been studied at the extreme ultraviolet wavelengths of 35.56±0.24 nm (34.87±0.24 eV) and 21.85±0.17 nm (56.74±0.44 eV) using a crossed ion-photon beam setup at the free-electron laser FLASH. Coincidence photoelectron and photofragment spectroscopy was performed at 21.85 nm, where both inner and outer valence ionization are allowed, and revealed that the XUV photolysis of H3O+ is by far dominated by ionization of outer valence electrons forming the 1A1 and 2E states of the dication H3O2+. The dications were found to dissociate into the channels H2O++H+ (72±4
