  • Description: Differential cross sections have been extracted from exclusive and kinematically complete high-statistics measurements of quasifree polarized →np scattering performed in the energy region of the d∗(2380) dibaryon resonance covering the range of beam energies Tn=0.98−1.29 GeV (√s=2.32−2.44 GeV). The experiment was carried out with the WASA-at-COSY setup having a polarized deuteron beam impinged on the hydrogen pellet target and utilizing the quasifree process dp→np+pspectator. In this way the np differential cross section σ(Θ) was measured over a large angular range. The obtained angular distributions complement the corresponding analyzing power Ay(Θ) measurements published previously. A SAID partial-wave analysis incorporating the new data strengthens the finding of a resonance pole in the coupled 3D3−3G3 waves.
