  • Crossed beams scattering study was carried out on the F+HD→DF+H reaction using highresolution H-atom Rydberg tagging time-of-flight technique. Vibrational state-resolved differential cross sections were measured, with partial rotational state resolution, at eight collision energies in the range of 2.51?5.60 kJ/mol. Experimental results indicated that the product angular distributions are predominantly backward scattered. As the collision energy increases, the backward scattered peak becomes broader gradually. Dependence of product vibration branching ratios on the collision energy was also determined. The experimental results show that the DF products are highly inverted in the vibrational state distribution and the DF (v′=3) product is the most populated state. Furthermore, the DF (v′=1) product has also been observed at collision energy above 3.97 kJ/mol.

Abstract: Crossed beams scattering study was carried out on the F+HD→DF+H reaction using highresolution H-atom Rydberg tagging time-of-flight technique. Vibrational state-resolved differential cross sections were measured, with partial rotational state resolution, at eight collision energies in the range of 2.51?5.60 kJ/mol. Experimental results indicated that the product angular distributions are predominantly backward scattered. As the collision energy increases, the backward scattered peak becomes broader gradually. Dependence of product vibration branching ratios on the collision energy was also determined. The experimental results show that the DF products are highly inverted in the vibrational state distribution and the DF (v′=3) product is the most populated state. Furthermore, the DF (v′=1) product has also been observed at collision energy above 3.97 kJ/mol.
