| 英文摘要 | We theoretically investigate the electron momentum distributions in orthogonally polarized two-color pulses with the Coulomb-Volkov distorted-wave approximation (CVA) theory and focus on the role of the Coulomb potential in the electron momentum distributions by comparing the CVA results with the strong-field approximation (SFA) simulations. Our results show that in comparison with the SFA simulations, the electron momentum distributions in CVA are in better agreement with the experimental observations and the time-dependent Schrodinger equation calculations. By analyzing the phase of the dipole moment, we find that the change of the electron momentum distributions in CVA can be ascribed to the different Coulomb corrections of the phases, which give rise to an enhanced contribution from the forward-rescattering electron and, on the other hand, a decrease of the contribution from the direct electron in the presence of the Coulomb potential. |
