Abstract: (Elsevier)
It is demonstrated that f 0 – a 0 mixing can lead to a comparatively large isospin violation in the reactions pN → da 0 , pd→ 3 He / 3 H a 0 and dd→ 4 He a 0 close to the corresponding production thresholds. The observation of such mixing effects is possible, e.g., by measuring the forward–backward asymmetry in the reaction pn→da 0 0 →dη π 0 .
