Abstract: The results of a model for meson-meson scattering are studied. The model is shown to be capable of on the one hand reproducing the scattering data, while on the other hand a quark-antiquark confinement spectrum can be determined. It is concluded that adopting the model-s formulation of the transition matrix elements for data analysis, it may serve as a link between experiment and quenched lattice calculations.
