Electron-impact double ionization of a model helium atom
Singleand double-ionization processes in electron scattering from a model helium atom are calculated by a direct solution of the time-dependent Schrödinger equation on a 3D lattice. The Coulomb interaction between the electrons is described by v(r1 ,r2)51/r. and all angular momenta are set to zero. The initial state is a product of the ground state of the model helium atom on a 2D lattice with ...
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...
متن کاملDouble multiphoton ionization of a model atom
A direct solution of the time-dependent Schrödinger equation ~TDSE! for a two-electron model atom in a strong electromagnetic field is used to extract probabilities for both single and double electron ionization. For three-photon ionization at a moderately strong intensity, the TDSE calculations find single ionization at 62%, single ionization with excitation at 10%, and double ionization at 3%...
متن کاملAttosecond Spatial Control of Electron Wavepacket Emission Dynamics and Electron-Electron Correlation in Double Ionization
Using orthogonally polarized two-color (OTC) laser fields on neon and coincidence momentum imaging we gain access to the Coulomb influence in single ionization on sub-cycle times, and demonstrate control over the two electron-emission dynamics in double ionization. We show that tuning the relative phase of the OTC fields allows dictating whether the two electrons are predominantly emitted in a ...
متن کاملElectron Correlation Effects in Nonresonant Multiphoton Ionization Processes
The role of electron correlations in nonresonant multiphoton processes of atoms is presented. The evidence for the validity of a lowest order perturbation theory (LOPT) approach for the laser field in the case of nonresonant processes is sketched. The growing consensus for a LOPT interpretation of even the multiply-charged ion spectra obtained with high intensity lasers is reviewed. Finally, a ...
