The scattering of neutrons by deuterons at high energies

Born’s approximation has been used to calculate total elastic and inelastic cross-sections and angular distributions for the scattering of neutrons by deuterons at incident energies of 100, 200 and 300 MeV. The nuclear potential has been taken to be a mixture of central and non-central interactions of the type √12 = I12 (1 - 1/2g + 1/2gσ1 σ2 + γS12) V(r), where S12 = r-23σ1. rσ2. r-σ1. σ2. Four types of isotopic factor I12, giving exchange properties of the neutral, charge exchange, symmetrical and Serber theories, have been investigated. The effect on the scattering of including the D wave of the ground state of the deuteron has been estimated.
