Coherence length of the KY(WO4)2 single crystal.

Potassium yttrium tungstate is a monoclinic crystal with space group C2/c. The specific X-ray investigations presented in this article determine the coherence scattering length for this crystal. The scattering profiles were obtained using a Philips MRD X-ray diffractometer. The Williamson-Hall method was used to determine the coherence scattering length and internal stresses.
