which were used in describing the shape and size of 7 atomic surfaces located at n0
n1
bc1 and ec0 with site-symmetry adapted surface harmonics
were refined by using quantitative convergent-beam electron diffraction technique
and a new high-dimensional model of icosahedral AlPdMn quasicrystal was obtained.With this new model and cut method
the atomic structure of icosahedral AlPdMn quasicrystal in 3-dimensional physical space was obtained.Comparing with other models in which the atomic surface at d0 is not taken into account
it shows more integrated shell structure.And the model given analytically can be applied mor extensively comparing with the 6-dimensional model in which 91 parameters are used in describing atomic surfaces.
