A Low Energy Neutron is a neutron that has a low kinetic energy, typically below 0.1 electron volts (eV). These neutrons are produced in nuclear reactions and are important in various fields, including nuclear physics and materials science. Their low energy allows them to be easily captured by atomic nuclei, making them useful for studying the structure of materials. In research, low energy neutrons are often used in techniques like neutron scattering, which helps scientists understand the arrangement of atoms in a substance. This information is valuable in developing new materials and improving existing ones, impacting industries such as pharmaceuticals and energy.
