+[[Scattering]] is normally thought of in the single-scattering limit. I.e. one imagines that incident x-rays pass through the material, and can be scattered into exit rays; one ignores the possibility of a scattered ray being scattered again. This is a reasonable approximation in many cases for [[x-ray]] scattering (and [[neutron]] scattering) since the scattering cross section is quite weak. However this is often a poor approximation for [[electron]] scattering since the interaction is so strong.

		+	==Kikuchi patterns==
		+	Sharp intersecting lines are sometimes observed in [[diffraction]] data for single-crystal or poly-crystalline materials, depending on the experimental geometry. In electron microscopy, multiple-scattering events create these '''Kikuchi patterns''', while in x-ray scattering they may be called '''Kossel lines'''. These lines arise due to multiple-scattering effect, e.g. when the x-ray source has high divergence.
		+
		+	Using a high-flux [[x-ray]] source ([[synchrotron]]), one can observe a related effect purely from the [[diffuse scattering]] undergoing multiple scattering. 'Multiple diffuse scattering' (DMS) can thus give rise to weak lines in a [[scattering]] image for crystalline materials (e.g. if one's sample is supported on a [[Material:Silicon\|silicon]] substrate).
