- Abstract
The ionization process of the hydrogen atom in two-color laser field is investigated based on nonBorn-Oppenheimer one-dimensional model. In this model, both electron and nucleus are described by the time-dependent Hartree equations. By numerically solving the equations, the influence of the relative phase ϕ of the laser field with the spatial distribution of electron and nucleus is investigated. For ϕ = 0, the electron is moved to the direction in which the maximum of the asymmetric combined electric field pointed. For ϕ = π/2, the electron is shown to be pulled in the opposite direction. © 2003 Wiley Periodicals, Inc. Int J Quantum Chem, 2004
