Quantum state tomography of Feshbach resonances in molecular ion collisions via electron-ion coincidence spectroscopy — •Edvardas Narevicius — Weizmann Institute of Science, 76100 Rehovot, Israel
During collisions coupling between the relative and internal atomic and molecular degrees of freedom lead to the formation of Feshbach resonances. The large phase space volume that particles explore in this metastable scattering state supports interference between many different quantum channels that include inelastic and reactive processes. We present a new method that allows us to measure simultaneously all the quantum channels for the Feshbach resonances that appear in collisions between vibrationally excited H2+ ion and noble gas atoms. Our quantum state mapping is based on coincidence ion-electron velocity map imaging spectroscopy.
