Abstract
It is demonstrated that f(0)-a(0) mixing can lead to a comparatively large isospin violation in the reactions pN --> da(0), pd --> He-3/(3)Ha(0) and d d --> He-4 a(0) close to the corresponding production thresholds. The obser vation of such mixing effects is possible, e. g., by measuring the forward- backward asymmetry in the reaction pn --> da(0)(0) --> d eta pi (0). (C) 20 01 Elsevier Science B.V.
