We report a quantum dynamics study of scattering on its lowest triplet state, for total angular momentum and total energies up to . This provides a benchmark example of indirect resonance-mediated reaction in presence of a conical intersection (CI). Visualization of time-dependent wave packets shows significant “looping” around the CI, which is facilitated by long-lived scattering resonances, predominant at low energies. State-to-state inelastic transition probabilities exhibit a highly oscillatory structure and pronounced geometric phase effects, which, in contrast to direct reactions, are more strongly marked at lower energies.
