The anomalous decrease in Debye-Waller factor is qualitatively interpretated. It is suggested using consistent parameters that the isomer shift decreases linearly with temperature in agreement with a second-order Doppler shift in the Debye approximation.QuasicrystalsPhononsNuclear resonancesAtomic hopping in AlCuFe quasicrystalarticle10.1016/0038-1098(95)00845-4
