neutron absorbing reaction

Neutron Capture - Radiative Capture - Nuclear PowerThe neutron capture is one of the possible absorption reactions that may occur. This capture reaction is also referred to as a radiative capture or (n, γ) reaction.neutron absorbing reaction,Neutron capture - WikipediaNeutron capture is a nuclear reaction in which an atomic nucleus and one or more neutrons . The absorption neutron cross-section of an isotope of a chemical element is the effective cross sectional area that an atom of that isotope presents to.
