Quantum dynamics study of the XÂ +Â F2 and FÂ +Â XF (XÂ =Â Mu, H, and D) reactions

► Reaction dynamics for X + F2 and FX + F′ (X = Mu, H and D) reactions were studied. ► Tunneling is very important for the Mu + F2 and F + MuF′ reactions. ► Reaction probability for F + MuF′ is enhanced around the reaction threshold.
