Evaluation of phonon distributions from satellites of X‐ray Bragg reflections is complicated by convolutions with spectral and angular distributions of the primary beam. Assuming only first‐order processes an integral equation fitting the experimental situation is derived and numerically solved. First results indicate higher phonon frequencies than previously obtained by optical Brillouin scattering on different samples and expected from Hutson and White [3] gain and McFee and Bateman [9] losses.
