Periodic diffraction patterns for 1D quasicrystals
(827K, Latex2e with 7 eps figures)

ABSTRACT.   A simple model of 1D structure based on a Fibonacci sequence with variable atomic spacings is proposed. The model allows for observation of the continuous transition between periodic and non-periodic diffraction patterns. The diffraction patterns are calculated analytically both using ``cut and project" and ``average unit cell'' methods, taking advantage of the physical space properties of the structure.
