Abstract

The total $n - p$ cross section has been measured using the neutron time-of-flight spectrometer at the Karlsruhe isochronous cyclotron. The measurements span the energy range from 0.7 to 32 MeV with statistical accuracy which varies from 0.2 to 1.0% and an energy resolution of 0.7 keV at 0.7 MeV and 200 keV at 30 MeV. No evidence was found for the recently reported oscillations in the total $n - p$ scattering cross section.
