## Abstract Causes of the formation of dislocation etch pits of different shape and size on {100} faces of cesium iodide crystals by an etchant composed from 25โ35 mg/1 CuCl~2~ ยท 2 H~2~O in 96% ethanol are studied. It is shown that one of the reasons of the change in the morphology of etch pits is
t If' the analysis is to be taken seriously, we can observe that there is one jog in the almost monotonic plot of activation energy as a function of temperature. At this jog, there is a shght upward jump in the plot which is also predicted by Hart.
We consider scattering of elastic waves on parallel wedge dislocations in the geometric theory of defects or, equivalently, scattering of point particles and light rays on cosmic strings. Dislocations are described as torsion singularities located on parallel lines, and trajectories of phonons are a
