Polarization Effects inn−pandp−pScattering

Abstract

Calculations have been made of the left-right asymmetry to be expected in neutron-proton scattering if polarized neutrons are used. The detection of such an asymmetry would be direct evidence of a tensor force interaction in the scattering. A 4 percent asymmetry might be expected at 100 Mev using a ($p,n$) exchange reaction as a source of 20 percent polarized neutrons. Effects are smaller in proton-proton scattering.
