MOSSBAUER DIFFRACTION AND INTERFERENCE STUDIES OF POLYCRYSTALLINE METALS AND ALLOYS

After a review of previous work on Mossbauer diffraction and interfere nce phenomena, the principles of the kinematical theory of Mossbauer d iffraction are presented. The emphasis is an how the spectroscopic cap abilities of the Mossbauer effect can be used to advantage in diffract ion studies on materials and condensed matter. Experimental results fr om Mossbauer powder diffractometry experiments are presented. These re sults identify the difficulties of Mossbauer powder diffraction experi ments, but also demonstrate that a unique chemical environment selecti vity is possible for Mossbauer diffraction. Future experiments with Mo ssbauer powder diffraction require the development of efficient detect ors, and some possibilities are suggested.
