Query: Raman interferometry between autoionizing states to probe ultrafast
  wavepacket dynamics with high spectral resolution   Photoelectron interferometry with femto- and atto-second light pulses is a
powerful probe of the fast electron wavepacket dynamics, albeit it has
practical limitations on the energy resolution. We show that one can
simultaneously obtain both high temporal and spectral resolution by stimulating
Raman interferences with one light pulse and monitoring the differential
changes in the electron yield in a separate step. Applying this spectroscopic
approach to the autoionizing states of argon, we experimentally resolved its
electronic composition and time-evolution in exquisite detail. Theoretical
calculations show remarkable agreement with the observations and shed light on
the light-matter interaction parameters. Using appropriate Raman probing and
delayed detection steps, this technique enables highly dfferential probing and
control of electron dynamics in complex systems.
