Description:
In this lecture the Bravais lattice is defined and several examples given. The basis vector is introduced for a general lattice. The theory of diffraction is derived, showing that Bragg refraction occurs when the momentum transfer equals a reciprocal vector. The reciprocal lattice is defined.The Ewald construction for X ?ray diffraction is explained. Emphasis is on the fact that the position of the diffraction spots depends only on the Bravais lattice. The basis only affects their intensities.
