摘要: Aluminium-based icosahedral phases (ABIP) have been investigated by neutron diffraction. Isomorphous substitution of manganese (a negative scatterer) Fe or FeCr (positive scatterers) allowed production contrast variations for the determination partial structure factors. Evidences centrosymmetry obtained.
