Mossbauer Effect for Surface Atoms: Iron-57 at the Surface of eegr A12O3.
The Mössbauer effect has been observed for Fe(57) atoms at the surface of eta Al(2)O(3). The Fe(57) is trivalent, and the quadrupole splitting found is consistent with a surface location. Anisotropy of thermal vibration relative to the surface is observed.
