Mössbauer Study of 57Co Implanted in Diamond

Abstract
A Mössbauer source of 57Co in diamond has been produced by implanting 57Co with an isotope separator directly into a diamond single crystal. The Mössbauer spectra taken at 80 and 300°K and in the [100] and [110] orientations displays two peaks of equal intensity. These two peaks can be interpreted as quadrupole splitting caused by the displacement of the iron interstitial from its site of tetrahedral symmetry.
