Spontaneous X‐ray parametric scattering from a diamond single crystal has been observed at the Photon Factory. The high perfection of the diamond single crystal and the small angular divergence of synchrotron radiation has enabled down‐converted X‐ray photon pairs to scatter into two small solid angles which satisfy the phase‐matching condition. High‐efficiency noise reduction was performed using avalanche photodiode detectors with good time resolution.
