Time resolved RIXS

.Resonant inelastic x-ray scattering (RIXS): this versatile x-ray spectroscopy is a combination of x-ray absorption and x-ray emission (see this review paper https://journals.aps.org/rmp/abstract/10.1103/RevModPhys.83.705 ). It is based on the resonant absorption/emission of x-rays and therefore chemically sensitive to specific ions in matter. This versatile probes can measure at the same time localized excitations like crystal field or charge transfer excitations and momentum resolved collective excitations (magnons and phonons e.g.).
