摘要：

By Fe-57 Mossbauer spectroscopy in a special experimental set-up we have shown the existence of Fe atomic jumps in Al62Fe25.5Cu12.5 perfect icosahedral quasicrystals. The (preliminary) results indicate that at 790 degrees C 20% of the Fe atoms are jumping at a time scale corresponding to 4 mu eV.
