Ionization Process of the Hydrogen Atom in Intense Laser Fields: Non-Born-Oppenheimer 1D Model Calculations

摘要

The ionization process of the hydrogen atom in two-color laser field is investigated based on non-Born-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 phi of the laser field with the spatial distribution of electron and nucleus is investigated.For phi=0,the electron is moved to the direction in which the maximum of the asymmetric combined electric field pointed.For phi=pi/2,the electron is shown to be pulled in the opposite direction.
