Neutron science involves the study of neutrons and their interactions with materials. It utilizes techniques like absorption, capture, diffraction, radiography, and scattering to analyze the structure, composition, and dynamics of materials. Copper isotopes and alloys play crucial roles as materials in neutron applications. Neutron detectors, spectrometers, radiography systems, reactors, and accelerators are essential equipment used in neutron science. This field finds applications in nuclear physics, particle physics, materials science, and various industries including non-destructive testing and materials characterization. Ongoing developments in neutron sources and techniques promise further advancements in neutron science, paving the way for exciting discoveries and technological innovations.
