Understanding neutron cross-sections is crucial in reactor physics because they quantify the probability of a neutron interacting with a nucleus in a specific way. A neutron cross-section represents the effective area that a nucleus presents to an incoming neutron for a particular interaction. These interactions include absorption, scattering, and fission. Absorption refers to the neutron being captured by the nucleus, potentially leading to a different isotope or a nuclear reaction. Scattering involves the ....
