Abstract

The tensor force has been taken into account in calculating the neutron-proton and proton-proton scattering at energies in the range from 100 to 200 Mev. Most of the calculations are performed in the Born approximation using a square well potential and the exchange models of Rarita and Schwinger. The rigorous scattering theory has also been applied to the neutron-proton scattering with the symmetrical force model at 100 and 200 Mev. The results show that the Born approximation is inaccurate at 100 Mev but not bad at 200 Mev. Comparison with the experimental neutron-proton scattering at 90 Mev shows that the theoretical cross section for symmetrical forces is too large by a factor of about 1.6.
