Neutron Optics: An Introduction to the Theory of Neutron Optical Phenomena and Their ApplicationsThis book presents the background theory and practical uses of neutron optics. Because the wave-particle duality applies to neutron beams generated in nuclear reactors, optical techniques have direct applications in this area of research. Optical instrumentation may consist of monochromators, prisms, lenses, or mirrors. The book assumes no knowledge of optics beyond undergraduate physics, and will be useful for those condensed matter physicists and chemists specializing in neutron theory and experimentation. This is the first North American volume in the newly inaugurated Oxford Series on Neutron Scattering in Condensed Matter. |
