  A structure model of atoms of two sizes, interacting with Lennard-Jones
potentials and simulated by molecular dynamics, was observed to freeze into a
decagonal quasicrystal dominated by Frank-Kasper coordination shells and
closely related to the Henley-Elser model for icosahedral quasicrystals.
Idealized structure models can be described as decorations of
triangle-rectangle and rhombus tilings. Equilibrium properties of the idealized
model have been determined by molecular dynamics simulations and a high
stability of the model and a low jump rate of the atoms have also been
observed.
