The effect of dislocations on the phase transition and scattering of light near the phase transition in a NH4Br crystal
Belousov M.V., Vol'f B.E.
An anomalous, small-angle scattering of light as a result of the phase transition in a NH4Br crystal was observed. It is shown that this anomaly is caused by a diffraction of light by the inclusions of the new phase, which are produced near the dislocations.
