Double-Slit Experiment Using Resonant Inelastic X-ray Scattering on An Iridium Oxide Crystal (image) University of Cologne Share Print E-Mail Caption An intense beam of high-energy X-ray photons (violet) hits two adjacent iridium atoms (green) in the crystal. This excites electrons in the atoms for a short time. The atoms emit X-ray photons which overlap behind the two iridium atoms (red) and can be analyzed as interference images.
