We have exposed isolated water molecules to short x-ray pulses from a free-electron laser and detected
momenta of all produced ions in coincidence.
By combining experimental results and theoretical modeling, we can
image the dissociation dynamics of water
after core-shell ionization and subsequent Auger decay
in unprecedented detail and uncover fundamental dynamical patterns
relevant for the radiation damage in aqueous environments.
