Quantum–classical approach to the reaction dynamics in a superfluid helium nanodroplet. The Ne2 dimer and Ne–Ne adduct formation reaction Ne + Ne-doped nanodroplet

The Ne + Ne@(4He)N reaction dynamics was studied using a quantum–classical approach. The angular momentum plays a critical role: the Ne–Ne adduct formation dominates the reactivity (instead of the Ne2 dimer) and quantized vortices are produced.
