Abstract
The cross-sections of the pd 3He , pd 3He and pd 3He reactions have been measured at the beam kinetic energies T p= 1360 MeV and T p= 1450 MeV using the CELSIUS/WASA detector setup. At both energies, the differential cross-section of the meson in the pd 3He reaction shows a strong forward-backward asymmetry in the CMS. The ratio between the pd 3He and pd 3He cross-sections has been analysed in terms of isospin amplitudes. The reconstructed invariant-mass distributions of the ,
3Heand
3He2 systems provide hints on the role of nucleon resonances in the 3 production process.
