Two-color x-ray pump x-ray probe study of the core-hole decay dynamics in XeF2
POSTER
Abstract
To resolve the femtosecond inner-shell dynamics and the subsequent induced electron transfer in a molecule, the core-hole decay dynamics in XeF2 have been directly studied using femtosecond time-resolved x-ray pump x-ray probe coincidence imaging. The study of XeF2 molecule allows us to compare the molecular core-hole decay with the atomic case, Xe atom. To study these processes, the recently developed capability at LCLS was used to generate two-color x-ray pulses with variable delay. A time and position sensitive detector has been used to record the ion fragments in coincidence. The correlated ion kinetic energies make it possible to select and assign different excitation pathways, being able to track the atomic and the molecular core-hole decay dynamics.
