Scientific Achievement
- Researchers in the Atomic, Molecular and Optical Sciences (AMOS) program revealed that the correlation-induced delay in the emission of electrons from different K-shells from laser-dressed photoionization measurements
Significance and Impact
- The measured delay in the emission of electrons was larger than expected and provides a sensitive probe of the correlated nature of electrons. User experiments have started exploring more complex molecular systems
Research Details
- Attosecond pulses from LCLS drive ionization in the presence of a strong, circularly polarized IR field which measures the relative delay in photoionization channels
- Comparison to high-level theory provides insight into the correlated nature of the electron emission
- Tunability of the FEL allows for the full reconstruction of the electronic wavepacket
