Abstract

An accurate measurement of the n-p differential cross section, in the angular range 116–180°, at 96 MeV is reported. Between 150° and 180° the angular distribution is steeper than earlier measurements and potential predictions. The sensitivity of the differential cross section to isospin-singlet, J≤4 phase-shift parameters was studied, and it was found that the observed difference at the most backward angles is sensitive mainly to L≥3 phase shifts.
