摘要Electron localization in the dissociation of the molecular ions H-3(+) and HeH2+ in an intense ultrashort ultraviolet laser pulse is studied with the Schrdinger equation. Two different dissociation channels, H-3(+) + n gamma -> H-2 + p and H-3(+) + n gamma -> H-2(+) + H, and HeH2++ n gamma -> He+ + p and HeH2++ n gamma -> alpha + H, for H-3(+) and HeH2+, are investigated, respectively. The numerical and analytical results both show that, for a molecular ion with an asymmetric double-well Coulomb potential, most electrons of the 1s sigma(g) state are localized at the potential well with lower energies. For electrons of the 2p sigma u state, most are localized at the potential well with higher energies when in a single ultraviolet laser pulse. Therefore, for H-3(+), most electrons of the dissociation state are stabilized at the potential well with higher energies (H+), for the lowest dissociation state is the 2p sigma(u) state. Most of the electrons of the dissociation state of HeH2+ are captured by the potential well with lower energies (He2+), because the lowest dissociation state is the 1ssg state and the 2p sigma(u) state is bounded.
