p↑p↑ scattering at sin

Using the PM1 polarized proton beam at SIN and a polarized target, the elastic p↑p↑ scattering as well as the inelastic channel p↑p↑→π+d have been studied between 400 and 600 MeV. For the elastic reaction, a sufficient number of spin dependent parameters has been measured in order to do a direct reconstruction of the scattering matrix between 38° cm and 90°cm.
