X-ray Raman scattering of Cu K_α radiation by solids of light elements has been studied. The scatterers were polycrystalline lithium, beryllium, boron and carbon. At the low-angle scattering it was clearly found that (1) the Raman scattering appears as a band, not as a line; (2) the shape of the band is quite similar to the spectrum of the K-absorption of the same material; and (3) the wavelength of the critical edge of the band shifts from the incident X-ray wavelength corresponding to the lowest excitation energy of the K-electron of the scatterers. The Raman band almost always overlapped the well-known Compton band, except for low-angle scattering. The shape of the whole spectrum consisting of the Compton- and Raman-band depends upon the scattering angle and the elements. After being analyzed, the intensity of the Raman scattering was confirmed to depend upon the scattering angle, θ, as (1 + cos^2 θ) sin^2 θ/2 as predicted by theory.
