Three electron coincidence scheme and momentum maps for Strong-field atomic ionization

POSTER

Abstract

Kinematically complete measurements of charged particles are a standard tool for strong-field ionization experiments nowadays that allow one for restoring ionization dynamics from the recorded electronic and ionic momenta1,2. Recent studies employ the well-developed two-electron coincidence technique3,4. At the same time the three-electron coincidence schemes are a clear next possible step. We simulate such a prospective experiment with our newly developed computational code that is based on numerical solution of time-dependent Schrödinger equation on a grid5-7. For the first time we obtain quantum-mechanical three-electron momenta distributions. These data are visualized with Dalitz plots and are further analysed. For the regime of femtosecond linearly-polarised near-infrared laser pulses acting on atomic target, we show that such plots are a valuable source of information on electronic rescattering that is sensitive to peak laser intensity and carrier-envelope phase. We pay a special attention to the effect of electronic spin configuration of particular atoms on the ionization process.
