than conventional Raman spectroscopy. Additionally, it can significantly reduce, or even eliminate the effects of fluorescence. X-Ray Raman scattering In the X-ray region, enough energy is available for making electronic transitions possible. At core level resonances, X-ray Raman scattering can become the dominating part of the X-ray fluorescence spectrum. This is due to the resonant behavior of the Kramers-Heisenberg formula in which the denominator is minimized for incident energies that equal a core level. This type of scattering is also known as Resonant inelastic X-ray scattering (RIXS). In the soft X-ray range, RIXS has been shown to reflect crystal field excitations, which are often hard to observe with any other technique. Application of RIXS to strongly correlated materials is of particular value for gaining knowledge about their electronic structure. For certain wide band materials such as graphite, RIXS has been shown to (nearly) conserve crystal momentum and thus has found use as a complementary bandmapping technique.
