Book excerpt: Muon science is rapidly assuming a central role in scientific and technological studies of the solid state within the disciplines of physics, chemistry, and materials science. Muon Science: Muons in Physics, Chemistry and Materials presents key developments in both theoretical and experimental aspects of muon spin relaxation, rotation, and resonance. Assuming no prior expertise in muon science, the book guides readers from introductory material to the latest developments in the field. The internationally renowned expert contributors cover topics in muon instrumentation and muon science applications that include muon production, beamlines and instrumentation, muonium chemistry, muon catalyzed fusion, fundamental muon physics, ultra-cold muons, magnetism, superconductivity, diffusion, semiconductors, simulations, and data analysis. The book maintains consistent notation and nomenclature throughout as well as cross-referencing and continuity between the contributions. It provides an excellent introduction to both new and experienced muon beam scientists and graduate students wishing to develop their knowledge and understanding of the subject.
