Neutron diffraction on piezoelectric vibrating resonators

A proposal was made to use neutron diffraction to investigate the dynamics of lattice vibrations of piezoelectric resonators. The results obtained explain some experimental facts published in the papers [9, 10, 13]. The obtained spectral distribution of diffracted neutrons is analogous to the spectral distributions of acoustically modulated -rays in the Mössbauer effect.The author is indebted to Assoc. Prof. J.
