Calculation of cross-section of incoherent elastic scattering of thermal neutrons

This paper is devoted to the consideration of neutron scattering on the crystal nuclei based on multiple scattering theories with application of the optical potential. In the approximation of the heavy nucleus the formula is derived for the distribution of the intensity of the scattered incoherent wave. The obtained results are applied to the calculation of the angle of deflection of a neutron in multiple scattering on nucleons of the nucleus.
