A new method for single crystal measurements: Application to Mossbauer spectra of mineral inclusions in diamond

The milliprobe technique has expanded the number of potential applications of Mossbauer spectroscopy, including the study of single crystals. Recent w ork has reported determination of the electric field gradient and mean-squa red displacement tensors in hedenbergite, a member of the pyroxene mineral group. Results are used to assess Mossbauer data collected from clinopyroxe ne single crystals that occur as inclusions in diamond.
