【 摘 要 】

The shapes of the occupation domains that correspond to the respective local environments of the clusters within a 12-fold packing model of icosahedral quasicrystals (iQCs) have been derived for the first time. The frequencies of appearance of the local environments of the clusters have also been calculated based on the exact volumes. The present results validate the frequencies obtained by a previous study using a statistical approach. Application of the 12-fold packing model to the F-type Al-based iQCs is discussed briefly.
