Abstract.

As the E852 and the GAMS Collaboration published their data for the dependence of the reaction \(\pi^-p\rightarrow\pi^0\pi^0n\) on the momentum transfered to the nucleon, questions rose, whether the \(K\bar{K}\)-molecule picture might be ruled out by their experiments. Here we report on our analysis of these data and our investigations into concerns raised in discussions, like the role of the \(NN\pi\pi\pi\) contact term. We find the molecule picture capable to explain the experimental data.
