Bs0→ J/ψπ0f0(980) and Bs0 → J/ψπ0a0(980) reactions, showing that the first is isospin-suppressed while the second is isospin-allowed. The reaction proceeds via a triangle mechanism, with Bs0 →J/ψK* K +c.c., followed by the decay K* →Kπ and a further fusion of KK into the f0(980) or a0(980). We show that the mechanism develops a singularity around the π0 f0(980) or π0a0(980) invariant mass of 1420 MeV, where the π0f0 and π0a0 decay modes are magnified and also the ratio of π0f0 to π0a0 production. Using experimental information for the Bs0 → J/ψK*K +c.c. decay, we are able to obtain absolute values for the reactions studied which fall into the experimentally accessible range. The reactions proposed and the observables evaluated, when contrasted with actual experiments, should be very valuable to obtain information on the nature of the low lying scalar mesons."> Triangle singularity enhancing isospin violation in B<sub>s</sub><sup>0</sup> → J/ψπ<sup>0</sup>f<sub>0</sub>(980) -
