Abstract
Electron localization during the dissociation of HD+ and is investigated by solving the corresponding time-dependent Schrödinger equation. Two different dissociation channels HD+ + nγH + d or HD+ + nγp + D and + nγH2 + p or + nγ for HD+ and are investigated, respectively. The numerical simulation demonstrates that for HD+ is in a single ultraviolet laser pulse, the electron localization distribution is symmetric for the symmetric distribution of the Coulomb potential wells though HD+ is a heteronuclear diatomic molecular ion. While for 92.6% electrons of all the dissociation events are localized at the potential well with higher energies (H+) for the asymmetric distribution of the Coulomb potential of H3+. When a terahertz pulse is used to steer the electron motion after the excitation of the ultraviolet laser pulse, more than 96.4% electrons of the dissociation state move opposite to the electric field force and stabilize at the one of the nuclei.
