Abstract
The elastic scattering cross section of deuterons for neutrons and protons of 90 and 350 Mev has been calculated, using the non-relativistic Born approximation. Two different approaches give roughly the same result: a total neutron-deuteron elastic cross section of about half the neutron-proton cross section at the same energy but sharply confined to small angles. The half-width at 90 Mev is about 15° in the laboratory system. The proton-deuteron elastic scattering is similar to the neutron-deuteron for large angular deflections, but at 90 Mev a difference due to the Coulomb repulsion should be noticeable within 10°. It is concluded that the assumption of a simple additivity of nucleon-nucleon cross sections for light elements is unjustified.
