	~~== Description ==~~

	~~XRS is an inelastic [[x-ray scattering techniques\|x-ray scattering]] process, in~~ which ~~a high-energy x-ray photon gives energy to a core electron, exciting it to an unoccupied state. The process~~ is in ~~principle analogous to [[X-ray absorption spectroscopy\|x-ray absorption]] (XAS), but the ''energy transfer'' plays the role of the x-ray photon ''energy absorbed'' in x-ray absorption, exactly as in~~
	~~Raman scattering in optics vibrational low-energy excitations can be observed~~
	by ~~studying the spectrum~~ of ~~light scattered from a molecule~~.

	~~Because~~ the ~~energy (and therefore wavelength) of the probing x~~-~~ray can be chosen~~
	~~freely and is usually in the hard x-ray regime~~, ~~certain constraints~~
	~~of soft x-rays in~~ the ~~studies of electronic structure of the material are~~
	~~overcome~~. ~~For example, soft x~~-~~ray studies may be surface sensitive~~ and ~~they require a vacuum environment. This makes studies~~ of ~~many substances, such as numerous liquids impossible using soft x-ray absorption~~. ~~One of the most notable applications~~ in ~~which x-ray Raman scattering~~ is ~~superior~~ to ~~soft x-ray absorption~~ is ~~the study of soft x~~-~~ray absorption edges~~ in ~~[[high pressure]]. Whereas high-energy x-rays may pass through a high-pressure apparatus like a [[diamond anvil cell]] and reach the sample inside the cell, soft x-rays would be absorbed by~~ the ~~cell itself~~.

	~~== History ==~~

	~~In his report of finding of~~ a ~~new type~~ of ~~scattering~~, ~~Sir [[Chandrasekhara Venkata Raman]] proposed that a similar effect should~~ be ~~found also in the x-ray regime~~. ~~Around the same time, B. Davis and D. Mitchell reported in 1928 on the fine-structure of the scattered radiation from graphite and noted that they had lines that seemed to~~ be ~~in agreement with carbon K shell energy. Several researchers attempted similar experiments~~ in the ~~late 1920s and early 1930s~~ but the ~~results could not always be confirmed. Often the first unambiguous observations~~ of the ~~XRS effect is credited~~ to ~~K. Das Gupta (reported findings 1959) and Tadasu Suzuki (reported 1964). It was soon realized that the XRS peak in solids was broadened by~~ the ~~solid~~-~~state effects and it appeared as a band, with a shape similar to~~ that ~~of a XAS spectrum~~. ~~The potential of the technique was limited until modern [[synchrotron light]] sources became available. This~~ is ~~due to the~~ very ~~small XRS probability of the incident photons, requiring radiation with~~
	~~a very high [[Intensity (physics)\|intensity]]~~. ~~Today,~~ the ~~XRS technique is rapidly growing in importance. It can be used to study [[XANES\|near~~-~~edge x-ray absorption fine structure]]~~ (~~NEXAFS or XANES) as well as [[extended x-ray absorption fine structure]] (EXAFS~~).

	~~== Brief theory~~ of ~~XRS ==~~

	~~XRS belongs~~ to ~~the class of non~~-~~resonant inelastic x-ray scattering, which has a [[Cross section (physics)\|cross section]]~~ of

	:~~<math>{d^2 \sigma \over d \Omega d E}= ({ d \sigma \over d \Omega })_{\rm Th} \times S(q,E)</math>~~.

	~~Here,~~ <~~math~~>~~(d \sigma / d \Omega )_{\rm Th}~~<~~/math~~> is the [[Thomson scattering\|Thomson cross section]], which signifies that the scattering is that of electromagnetic waves from electrons. The physics of the system under study is buried in the ''dynamic structure factor'' <math>~~S(q~~,~~E)</math>~~, ~~which~~ is a ~~function of momentum transfer <math>q</math> and energy transfer <math>E</math>~~. ~~The dynamic structure factor contains all non~~-~~resonant electronic excitations, including not only the core~~-~~electron excitations observed~~ in ~~XRS but also e.g. [[plasmon]]s,~~ the ~~collective fluctuations of [[valence electron]]s, and [[Compton scattering]].~~

	~~couples to the charge of the electron~~. ~~Because of this~~, the ~~momentum transfer~~
