For this purpose, a quasilattice is constructed by the grid method. As this model crystal shows, in a quasicrystal also the lattice points are arranged in strings and planes and form pronounced axial and planar channels. Their occupation by lattice points is, however, not constant, but exhibits a wide density distribution in contrast to periodic crystals. Manganese atoms were placed at the lattice points and backscattering yield profiles of 750-keV He+ ions were obtained in a channeling computer simulation. Pronounced channeling minima are observed in the profiles for axial as well as planar channeling.eninfo:eu-repo/semantics/openAccessIonenkanal , Quasikristall530article
