Light-pulse pairs reveal the femtosecond decay of an inner-shell hole in xenon atoms
Phys.org ·
The Brief
- Researchers at the UVSOR Synchrotron Facility (Institute for Molecular Science, Japan) and partner institutions observed the decay of a xenon 4d core hole directly in the time domain.
- The study used pairs of phase-coherent extreme ultraviolet pulses to track the inner-shell vacancy as it decays on a femtosecond timescale.
Why it matters
Direct time-domain measurements of core-hole decay in a simple atom provide experimental benchmarks for ultrafast atomic physics and for interpreting time-resolved X-ray and EUV spectroscopy.
