Seyfarth (Forschungszentrum Jülich, Germany | | Abstract: | The data from the first measurement, performed at ANKE/COSY, of the unpolarized cross section of the reaction $pd o (pp)n$ in the kinematics of backward elastic $pd o dp$ scattering at proton-beam energies between 0.6 and 1.9 GeV are analyzed in a phenomenological approach. The $pd o (pp)n$ data and the triplet cross section of the reaction $pd o (pn)p$, calculated from the $pd o dp$ data on the basis of the Fäldt-Wilkin extrapolation, are used here to derive the ratio $zeta$ of the singlet production matrix element squared to the triplet one. This ratio, defined in our earlier analysis of $pd o (pn)p$ data in a largely model-independent way, depends on the dynamics of the $pd$ interaction. We find here $zetaapprox 0.02$ and show that the smallness of this value may point toward softness of the deuteron at short NN distances. | | Source: | arXiv, nucl-th/0211001 | | Services: | Forum | Review | PDF | Favorites | |
