The elastic and inelastic scattering from x ‐cut quartz single crystal is investigated by means of Mössbauer diffractometry from the (11 2 0) Bragg plane using 57 Co‐source and a Mössbauer absorber for the energy analysis. When the crystal is excited to piezo‐electric vibrations in the MHz‐range, inelastically scattered quanta are resolved. The phonon energies are in the range 40 neV < < ħΩ q < 150 neV.
