Intermediate-State Coulomb-Corrected Strong-Field Approximation for Nonsequential Double Ionization
We present a refined strong-field approximation (SFA) theory incorporating the intermediate-state Coulomb interaction for nonsequential double ionization (NSDI). By introducing the Coulomb−Volkov wave function into the intense-field many-body S-matrix theory, we develop an intermediate-state Coulomb-corrected strong-fi...
