Neutron-induced reactions are most common in nuclear and analytical chemistry because neutrons are electrically neutral particles, which allows them to penetrate the positively charged nucleus without facing Coulombic repulsion. This characteristic makes neutrons highly effective in initiating nuclear reactions even at relatively low energies. Neutrons can interact directly with nuclei to produce activation, fission, or transmutation reactions. In electroanalytical and other analytical methods, neutron activation analysis (NAA) exploits this property, where samples are irradiated with neutrons to produce radioactive isotopes that can be detected with high sensitivity, making the technique highly precise and
