Neutron capture is the process in which a neutron is absorbed by an atomic nucleus, leading to the creation of a more massive and unstable nucleus. Some synonyms for neutron capture include neutron absorption, neutron capture reaction, and neutron-induced reaction. These terms are often used in the field of nuclear physics and engineering to describe the various ways in which neutrons interact with atomic nuclei. Other related terms include fission, fusion, and radioactive decay, all of which involve changes in the composition and energy of atomic nuclei. Neutron capture is a crucial process in nuclear reactions, including nuclear power generation and the production of isotopes for medical and industrial applications.
