WebIf the interaction between the nucleus and the neutron fails to produce subsequent neutrons, the process is considered a radiative or parasitic neutron capture. Usually a capture event produces an excited state in the nuclei, with a subsequent gamma emission to return the nucleus back to the ground state so the symbol ( n, γ) is used.
