Scattering resonances play a central role in collision processes in physics and chemistry. They help buildingan intuitive understanding of the collision dynamics due to the spatial localization of the scattering wavefunctions. For resonances that are localized in the reaction region, sharp peaks inthereaction rates are the characteristic signature, observed recentlywith state-of-the-art experiments in low energy collisions. If, however, the localization occurs outside of the reaction region, only the elastic scattering is modified. This may occur due to above barrier resonances,the quantum analogue of classical orbiting. By probing both elastic and inelastic scattering experimentally, wedifferentiate between the nature of quantum resonances - tunneling vs above barrier - and corroborate our findings by calculating the corresponding scattering wavefunctions.
