Abstract :
Parametric down conversion of X-ray photons in diamond crystals was detected in six experiments, all using the phase matching scheme first employed in the X-ray regime by Eisenberger and McCall (Eisenberger and McCall, Phys. Rev. Lett. 26 (1971) 684). The conversion events were detected by a combination of time correlation spectroscopy and energy discrimination. The time correlation spectra gave a direct comparison of the conversion rate over the accidental coincidence rate.
