Abstract：
A model to calculate the neutron induced radiative capture spectra in the resonance region is proposed. Three reaction mechanisms has been taken into account, i.e. statistical processes, potential capture and the capture in the compound elastic channel. The thermal neutron capture spectra and multiple numbers of photon for some nuclei in the 3s resonance region: ⁵¹V, ⁵⁵Mn, ⁵²Cr etc. are calculated. It is shown that the including of the radiative capture in the compound elastic channel will improve obviously the coincidence of the theoretical calculations with the experiments, especially in the high energy parts of the spectra.
