Electron Diffraction and Crystal Structure
instructor.physics.lsa.umich.eduElectron Diffraction and Crystal Structure 1. Introduction In classical mechanics we describe motion by assigning momenta to point particles. In quantum mechanics we learn that the motion of particles is also described by waves, with the crucial parameters of the two viewpoints related through the de Broglie relation: != h p [1]
