Progress of Theoretical Physics, Apr 1957
With the help of a potential so chosen as to, in a sense, just satisfy the saturation requirements and the various experimental data on the deuteron, and nucleon-nucleon scattering at low energies, the neutron proton differential scattering cross-section σ(θ) is calculated at 100 Mev and 260 Mev in Born's approximation. The error due to the use of Born's approximation at 100 Mev is estimated. The calculated cross-sections are in fair agreement with experiment and indicate the desirability of making an exact phase shift calculation of σ(θ) for this potential.
