Measurement of proton kinetic-energy distributions from dissociative photoionization of H$sub 2$ is reported, for incident-photon energies up to 41 eV. Data are presented for transitions involving the 1ssigma/subg/ ground state and higher states of H$sub 2$ $sup +$. At a photon energy of 41 eV, direct ionization involving the 2psigma/subu/ state accounts for approximately one-half of the dissociative ionization; other processes, autoionization or direct ionization involving states of higher energy than 2psigma/subu/, account for the remainder.
