Abstract
We discuss how to extract observables from an inhomogeneous vertex Bethe-Salpeter equation without resorting to the corresponding homogeneous equation. As an example we present a prediction for the decay width of the or meson. We also attempt to identify the momentum range contributing to a vector meson's decay constant.
