The kinetic energy and angular distributions of H+ as a function of 405 nm femtosecond laser intensity are experimentally measured by using velocity map imaging technique. The reaction pathways of dissociation channels, H+2→H++H and H2+2→H++H+, are discussed. The former is due to the direct one-photon pathway via the 1ω crossing, and the latter stems from Coulomb explosion of H2+2. Ionization of H+2 to H2+2 starts from bond softening. The relative yield of fragment peak indicates that dissociation and ionization of H+2 are competitive. The lower laser intensity emphasizes the dissociation of H+2, and the higher laser intensity favors the ionization of H+2.
