| 英文摘要 | we experimentally measured the kinetic energy and angular distributions of fragment ion h+ of h-2 as a function of 810 nm femtosecond laser intensity by using velocity map imaging technique. the reaction pathways of dissociation channels h-2(+) -> h+ + h and h-2(2+) -> h+ + h+ are proposed. the analysis of the angular distribution indicates the net two-photon pathway via the 3 omega crossing dominates over the direct one-photon pathway in channel h-2(+) -> h+ + h. the ionization of h-2(+) to h-2(2+) may be initiated by bond softening and above-threshold dissociation. the relative yield of fragment peaks indicates that dissociation and ionization of h-2(+) are competitive. the lower laser intensities emphasize the dissociation probability of h-2(+), and the higher laser intensities favor higher ionization stages. |
