Nuclear cross section is a fundamental concept in nuclear physics and particle physics that quantifies the likelihood of a specific interaction (or scattering event) occurring between particles, such as a neutron and a nucleus or between two nuclei. It is essentially a measure of the probability of an interaction taking place and is expressed in units of area, typically in barns (1 barn = \\(10^\{-24\}\\) cm²).
