Radiative capture of neutrons by the lightness nuclei

The new theoretical and experimental data on neutron cross sections for radiative capture in case of hydrogen, deuterium and helium-3 nuclei are given and analyzed in the review. The following questions are under discussion: wave function symmetry selection rule in (n, γ)-reaction for a new nucleon systems, exchange currents effects, use of detailed balance in order to obtain (n, γ)-cross sections two-photon radiative capture and some others. Several problems are pointed in solving of which one can obtain new information on the few body wave functions and the properties of nucleon-nucleon interactions
