Subcycle 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 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 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 کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Double Ionization of He by Proton Impact
Double ionization of helium by charged particle impact belongs to the most simple and therefore fundamental, unsolved dynamical many-electron problems in atomic physics. At medium to small perturbations (Z/v < 1; Z, v projectile charge and velocity) mainly two mechanisms contribute to the double ionization cross section: First, one electron can be ionized directly by the interaction with the pr...
