Determining the nature of quantum resonances by probing elastic and reactive scattering in cold collisions
Scientists from Freie Universität Berlin, Israel's Weizmann Institute of Science, and the Netherlands' Radboud University have demonstrated two types of quantum resonances: tunneling resonances and above-barrier resonances. The team of physicists and chemists combined the merged-beam technique with VMI detection assisted by near-threshold photoionization to resolve the resonances and corroborated their findings by calculating the corresponding scattering wavefunctions.
