Electron impact ionization of H_2+
The electron impact ionization cross section of H2 is calculated using a distortedwave approximation. The calculated cross section is compared to the experimental results of Peart and Dolder. The simplicity of the system allows an assessment of the accuracy of the distorted-wave approximation without complications from inaccuracies in the target state, initial continuum state, or final continuu...
متن کاملNonsequential double ionization of molecules
Double ionization of diatomic molecules by short linearly polarized laser pulses is analyzed. We consider the final stage of the ionization process, that is the decay of a highly excited two electron molecule, which is formed after rescattering. The saddles of the effective adiabatic potential energy close to which simultaneous escape of electrons takes place are identified. Numerical simulatio...
متن کاملLaser-assisted and laser-induced electron-impact ionization during nonsequential double ionization of He
Two-electron sum-momentum distributions from nonsequential double ionization of He in an intense laser field are analyzed. The results of a S-matrix calculation show that the inelastic scattering of the first electron with the residual ion is best considered as a ~internal! laser-induced impact ionization. The parallel component of the sum momentum is found to be largest when the prescattering ...
متن کاملElliptical trajectories in nonsequential double ionization
Using a classical ensemble method, nonsequential double ionization is predicted to exist with elliptical and circular polarization. Recollision is found to be the underlying mechanism, and it is only possible via elliptical trajectories.
متن کاملSubcycle control of electron-electron correlation in double ionization.
Double ionization of neon with orthogonally polarized two-color (OTC) laser fields is investigated using coincidence momentum imaging. We show that the two-electron emission dynamics in nonsequential double ionization can be controlled by tuning the subcycle shape of the electric field of the OTC pulses. We demonstrate experimentally switching from correlated to anticorrelated two-electron emis...
