Abstract

We present first results of simultaneous attosecond streaking measurements of shake-up electrons and Auger electrons emitted from xenon. We extract relative photo-emission delays for electrons emitted from the 4d, 5s and 5p subshell, as well as for the 5p −2 5d correlation satellite (shake-up electrons).

Highlights

  • The recent advances in attosecond physics revealing an emission delay between electrons emitted from valence states and deeper bound 4f states in tungsten [1] and from the 2p and 2s subshells in neon [2] have provoked and will continue to provoke questions about the physics of photoionization

  • We present first results of simultaneous attosecond streaking measurements of shake-up electrons and Auger electrons emitted from xenon

  • We present experimental data obtained using this method from an atomic system, xenon, from which more different electron wavepackets including shake-up electron wavepackets are emitted, and where a spectral overlap of some of these wavepackets can be observed

Summary

Introduction

The recent advances in attosecond physics revealing an emission delay between electrons emitted from valence states and deeper bound 4f states in tungsten [1] and from the 2p and 2s subshells in neon [2] have provoked and will continue to provoke questions about the physics of photoionization. We present first results of simultaneous attosecond streaking measurements of shake-up electrons and Auger electrons emitted from xenon.
