摘要：
We have measured positron annihilation lifetime spectra and discuss the first shell of atomic cluster in quasicrystal Zn-Mg-Sc and the approximant crystal Zn17Sc3 by comparing with Cd-Yb icosahedral quasicrystals and the approximant crystal Cd6Yb. These measurements suggested that vacancy-like open space might exist around the first shell of atomic cluster.
