Neutron-Proton Polarization and Differential Cross Section at 128 Mev

Abstract

A 42% polarized neutron beam of 128 Mev average energy has been used to measure the $n\ensuremath{-}p$ differential cross section and polarization. A range telescope detected recoil protons from a liquid hydrogen target placed in the beam. The following values were obtained: The errors quoted do not include the 7% uncertainty in the normalization of the cross-section data or the 8% uncertainty in the normalization of the polarization data.
