In crystallography, the Laue equations give three conditions for incident waves to be diffracted by a crystal lattice. They are named after physicist Max von Laue (1879–1960). They reduce to Bragg's law. ==Equations== Take to be the wavevector for the incoming (incident) beam and to be the wavevector for the outgoing (diffracted) beam. is the scattering vector (also called transferred wavevector) and measures the change between the two wavevectors. Take to be the primitive vectors of the crystal lattice. The three Laue conditions for the scattering vector, or the Laue equations, for integer values of a reflection's reciprocal lattice indices (h,k,l) are as follows: : : : These conditions say that the scattering vector must be oriented in a specific direction in relation to the primitive vectors of the crystal lattice. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Laue equations」の詳細全文を読む スポンサード リンク
