      abstract     = {The photofragmentation of the water cation $H_2O^+$ through
                      dicationic states has been studied at 35.0 ± 0.2 nm (35.4
                      ± 0.3 eV) and 21.8 ± 0.2 nm (56.8 ± 0.5 eV) with a
                      crossed ion-photon beams experiment at the free electron
                      laser FLASH. The dissociation of the dications is found to
                      be similar at the two wavelengths and to proceed into $O^0 +
                      2H^+$, $OH^+ + H^+$, and $O^+ + H_2^+$, with determined
                      ratios $\sigma_{OH^+ + H^+}/\sigma_{O^+ + H_2^+}$= 4.2 ±0.3
                      and $\sigma_{OH^+ + H^+}/\sigma_{O^+ + 2H^+}$>0.7. The
                      measured kinetic-energy releases for these processes are
                      consistent with three-body breakup ($O^0+2H^+$) occurring
                      mainly through the $2^3A''$ and $2^1A''$ states of
                      $H_2O_2^+$ and two-body breakup ($OH^+ + H^+$) occurring
                      through $X^3A''$, $1^3A′$, and $1^1A''$ states of
                      $H_2O_2^+$, as predicted in a recent theoretical study
                      [Gervais et al., J. Chem. Phys. 131, 024302 (2009)]. In
                      addition to the kinetic-energy releases, we also report on
                      fragment correlation in the three-body channel where the two
                      protons carry the major part of the released momentum.},
