Abstract
The lattice parameter a of face-centred icosahedral Al70.3Pd21.7Mn8.0 was d etermined using X-ray pow der diffraction in the temperature range between 15 K and 300 K. Fitting its temperature dependence by a polynomial of secon d order a linear thermal expansion coefficient alpha(T)= 1.19(15).10(-6) K- 1 + 4.40(21).10(-8) K-2 T has been derived. After long-period low temperatu re ageing the appearance of an additional reflection at /k/ = 1.716 Angstro m(-1) was observed.
