摘要：

Final results for total cross section differences DELTA-sigma-T and DELTA-sigma-L measured with a polarized neutron beam transmitted through a polarized proton target are presented. Measurements were carried out at SATURNE II, at 11 energies between 0.63 and 1.1 GeV for DELTA-sigma-T and at 9 energies between 0.312 and 1.1 GeV for DELTA-sigma-L. The results are compared with measurements at PSI and LAMPF as well as with DELTA-sigma-L data points deduced from p-d and p-p transmission experiments at the ANL-ZGS. The present results together with the corresponding pp data allow to determine two of the three imaginary parts of forward scattering amplitudes for isospin I = 0.
