We have directly observed a Feshbach-resonance by Coincidence-detection of Ions and Electrons in Penning Ionization Collisions. 



We present a new experimental approach for observing molecular dynamics involving neutral particles and ions that is capable in providing state-to-state mapping of the dynamics.
