The pp total cross section difference between pure transverse spin states was measured in the laboratory momentum range 1–3 GeV/ c . Significant differences were found and these differences show striking energy dependence. This structure is in disagreement with the predictions of simple exchange models.

Measurement of the Spin Dependent Neutron Proton Total Cross-section Differences $\Delta \Sigma^- T$ and $\Delta \Sigma^-$l Between 0.63-{GeV} and 1.08-{GeV}

We present first measurements of total cross section differences Δσ T and Δσ L for a polarized neutron beam transmitted through a polarized proton target. Measurements were carried out at SATURNE II, at 0.63, 0.88, 0.98 and 1.08 GeV. The results are compared with Δσ L data points deduced from p-d and p-p transmission experiments, and with phase shift analyses predictions. The present results together with the corresponding pp data yield two of the three spin dependent forward scattering amplitudes for isospin I =0.

Statistical errors are statistics and random fluctuations. Systematic error contains uncertainties in beam and target polarizations, hydrogen content of the target, and residual error due to misalignment.
