A beam of pions (T) is incident on a proton target, giving rise to the process Tpn+t+T (A). Assuming that the decay proceeds through strong interactions, the total isospin I and its third component Il3 for the decay products, are (a) I= (c)=- b) I=h=5 1 (d)I, =-5 (B). Using isospin symmetry, the cross-section for the above process can be related to that of the process (a) 7n prz (c)Tnpr'r (b) Tpīr7 (d) TP-nr'z
