FAST TRACK COMMUNICATION Origin of species dependence of high-energy plateau photoelectron spectra
We analysed the energy and momentum distributions of high-energy ‘plateau’ photoelectrons. These electrons, with energies above 4Up (Up is the ponderomotive energy), have been understood qualitatively as due to the backscattering of laser-induced returning electrons by the target ion. Here, we establish a quantitative rescattering (QRS) theory to show that the species and laser-intensity depend...
متن کاملElastic scattering and impact ionization by returning electrons induced in a strong laser field
We study elastic scattering and impact ionization by returning electrons induced in a strong laser field based on the recently developed quantitative rescattering theory. The high-energy angle-resolved photoelectron spectra of molecules in strong fields are attributed to elastic scattering of the returning electrons with the parent ion. We demonstrate that the high-energy photoelectron spectra ...
متن کاملPlateau in Above-Threshold-Ionization Spectra and Chaotic Behavior in Rescattering Process
An improved quasistatic model is used to describe the ionization process of atoms in intense linearly polarized fields. Numerical calculations of AboveThreshold-Ionization (ATI) energy spectra and photoelectron angular distributions (PAD) of hydrogen atoms reveal clearly plateau and side lobe structures, which are in good agreement with recent ATI experiments. Our results show that, the existen...
متن کاملElectron rescattering in above-threshold photodetachment of negative ions.
We present experimental and theoretical results on photodetachment of Br(-) and F(-) in a strong infrared laser field. The observed photoelectron spectra of Br(-) exhibit a high-energy plateau along the laser polarization direction, which is identified as being due to the rescattering effect. The shape and the extension of the plateau is found to be influenced by the depletion of negative ions ...
متن کاملSingle and Multiple Electron Dynamics in the Strong Field Limit
High precision photoelectron energy and angular distributions in helium and neon atoms for a broad intensity range reflect the change in the continuum dynamics that occurs as the ionization process evolves into the pure tunneling regime. Elastic rescattering of the laser-driven free electron from its parent ion core leaves a distinct signature on the spectra, providing a direct quantitative tes...
