Abstract
The d d→α X0 reaction at beam energies close to the η threshold shows very strong structure in the missing mass corresponding to the ABC enhancement. The deuteron tensor analysing power Ayy, and the slope of the vector analysing power Ay with respect to angle, have been measured for this reaction around the forward direction. Both signals are small, and their variations with the α-particle momentum are in broad agreement with a theoretical model in which each pair of nucleons in the projectile and target deuterons undergoes pion production through the NN→dπ reaction.
