Experimental studies of inelastic X-ray and γ-ray scattering

Studies of inelastic scattering of X-rays and γ-rays of energies higher than 30 keV performed with the help of NaI(Tl) and semi-conductor detectors of moderate and good resolution, respectively, are considered in the first part of this review. Theoretical treatments based on the non-relativistic (e2/2mc2) A2 interaction term, the impulse approximation, the incoherent scattering function approximation, the (−e/mc) P·A interaction term, and the...
