  A tenet of time-resolved spectroscopy is -faster laser pulses for shorter
timescales- . Here we suggest turning this paradigm around, and slow down the
system dynamics via repeated measurements, to do spectroscopy on longer
timescales. This is the principle of the quantum Zeno effect. We exemplify our
approach with the Auger process, and find that repeated measurements increase
the core-hole lifetime, redistribute the kinetic energy of Auger electrons, and
alter entanglement formation. We further provide an explicit experimental
protocol for atomic Li, to make our proposal concrete.
