Abstract

Neutron-proton and proton-proton elastic scattering are compared in the momentum range from 3 to 7 GeV/c. At the same incident momenta the $\mathrm{np}$ and $\mathrm{pp}$ diffraction peaks have similar slopes, and both peaks shrink with increasing momentum. Over this momentum range the 90\ifmmode^\circ\else\textdegree\fi{} $\mathrm{np}$ cross section is 1.1 \ifmmode\pm\else\textpm\fi{} 0.1 times the 90\ifmmode^\circ\else\textdegree\fi{} $\mathrm{pp}$ cross section. Differential cross sections for nucleon-nucleon scattering with isospin 0 are compared with those for isospin 1.
