Abstract = {{We report the observation of parametrically down-converted x-ray signal
   photons at photon energies that correspond to idler photons at optical
   wavelengths. The count-rate dependence on the angles of the input beam
   and of the detector and on the slit sizes agrees with theory within the
   experimental uncertainties. The nonlinear susceptibility, which we
   calculated from the measured efficiencies, is comparable to the
   nonlinear susceptibility evaluated from the measurements of x-ray and
   optical wave mixing. The results of the present Letter advance the
   development of a spectroscopy method for probing valence-electron
   charges and the microscopic optical response of crystals with
   atomic-scale resolution.}},
