Full quantum state resolved scattering dynamics of the F+H2→HF+H reaction at 5.02 kJ/mol

A crossed molecular beams, state-to-state scattering study, vas carried out on the F+H-2 -> HF+H reaction at the collision energy of 5.02 kJ/mol, using the highly sensitive H atom Rydberg tagging time-of-flight method. All the peaks in the TOF spectra can be clearly assigned to the ro-vibrational structures of the HF product. The forward scattering of the HF pro duct at v'=3 has been observed. The small forward scattering of the HF product at v'=2 has also been detected. Detailed theoretical analysis is required in order to fully understand the dynamical origin of these forward scattering products at this high collision energy.
