主　　题：strong-field ionization Wigner-distribution-like ionization instant 

摘      要：A Wigner-distribution-like(WDL)function based on the strong-field approximation(SFA)theory is used to investigate the ionization time of the photoelectron emitted from the initial states with different magnetic quantum number m in elliptically polarized electric *** saddle-point method is adopted for *** different m states,a discrepancy exists in the WDL distributions of the photoelectrons emitted in a direction close to the major axis of the laser field *** on the saddle-point analysis,this discrepancy can be ascribed to the interference between electrons ionized from two tunneling *** results show that the relationships between the tunneling instants and kinetic energy of photoelectrons are the same for different m initial states when the Coulomb potential is not *** work sheds some light on the ionization-time information of electrons from different magnetic quantum states.
