碩士 === 淡江大學 === 物理研究所 === 82 === We have measured the Mn, Ge K-edge and Pd L3-edge XAFS spectra
of Al70Pd12.5Mn17.5 and Al60Pd12.5Mn17.5Ge10 quasicrystals at
room temperature,in fluorescence and total electron yield mode.
At the Mn and Ge K-edge, the absorption spectra are analyzed
with a description of local atomic structure based on the
Mackay Icosahedral Model. Furthermore, we use the fitting
method to deduce the coordinate numbers, bond distance and
Debye-waller factors of the first-neighbor of Mn and Ge. In
the case of the Pd L3-edge analysis, we find the density of 4d
unoccupied stateds above the Fermi level have no change between
two different quasicrystals.
