Topological part of the interaction of phonons with dislocations and disclinations

A source moving uniformly near a linear defect (dislocation or disclination) loses energy, radiating longitudinal and transverse acoustic vibrations by virtue of the diffraction of its self-field by the long-range field of the lattice displacements. The spectral loss density per unit length of a defect is calculated for a disclination and a screw dislocation. The obtained results are compared with the results of the theory of transition radiation of sound by point defects.
