Abstract:
Cross sections and strength functions in neutron reactions on 147Sm were evaluated from slow resonance neutrons up to 14 MeV neutrons. For their descriptions the neutron resonance parameters, transmission coefficients for exit channels and the Hauser – Feshbach formalism were included. The theoretical evaluations are performed by using Talys free software and author’s computer programs. The obtained cross sections and strength functions are compared with experimental data in order to explain possible non statistical effects reported previously by some authors on the distributions of alpha widths
