Spin correlations and analyzing powers in pp -> π+d between 447 and 578 MeV

The analyzing power Asub(no)(THETA) and the spin correlation parameters Asub(nn)(THETA), Asub(ss)(THETA), Asub(kk)(THETA), Asub(sk)(THETA) have been measured in the reaction pp -> π+d over a large angular range at 447, 496, 515, 538 and 578 MeV. The experiments were performed at SIN, using a polarized proton beam and a polarized proton target. The measured angular distributions have been fitted to phenomenological partial wave expansions in terms of Legendre polynomials and associated functions. Results have been compared with several calculations based on different theoretical models. At the lower energies, the agreement is reasonably good; however, none of the theories is able to explain all the results in a satisfactory way. (orig.)
