Abstract
We report a measurement of the spin-dependent total cross section ratios De lta sigma(T)/sigma(tot) and Delta sigma(L)/sigma(tot) of the pp --> pp pi(0 ) reaction between 325 and 400 MeV.: The experiment was carried out with a polarized internal target in a storage ring. Nonvertical beam Polarization was obtained by the use of solenoidal spin rotators. Near threshold, the kn owledge of both spin-dependent total cross sections is sufficient to deduce the strength of certain participating partial waves; free of any model.
