Quantum calculations of nonadiabatic 2A1-2B2 conical-intersection effects in the reactions N(4S)+O2(X3Σg-) and N(4S) + O2(A3Δu)

The dynamics of N(4S)+O2(X3Σg-), (1), and N(4S) + O2(A3Δu), (2) is investigated for some O2 vibrational and rotational states, v0 and j0. Reaction (1) is direct and its probabilities and cross sections increase with the collision energy, are slightly affected by nonadiabatic couplings, increase with v0, and do not depend on j0. Reaction (2) is indirect and its probabilities and cross sections decrease with the collision energy, are significantly lowered by nonadiabatic couplings, and decrease with both v0 and j0.
