Lattice

Name:
Lattice
Detailed information:
(1) The structural arrangement of atoms in a crystal. Accurate information is obtained by X rays, which are diffracted by the lattice at various angles. As the atoms are from 1.5 to 3 Å apart in most crystals, the lattice acts as a diffraction grating.See crystals; Dislocation.(2) The array of nuclear fuel elements and moderator in a nuclear reactor.
