Quantum mechanical integral and differential cross sections have been calculated for the
title reaction at the three collision energies studied in the 1985 molecular beam experiment
of Lee and co-workers, using the new ab initio potential energy surface of Stark and Werner
preceding paper. Although the overall agreement between the calculated and experimental
center-of-mass frame angular distributions is satisfactory, there are still some noticeable
differences. In particular, the forward scattering of HF (v 3) is more pronounced in the …

Quantum-mechanical integral and differential cross-sections have been calculated for the
title reaction at the two collision energies (Ecoll= 1.35 and 1.98 kcal mol-1) studied in the
1985 molecular beam experiment of Lee and co-workers, using the new abinitio potential-
energy surface of Stark and Werner. The DF+ H product channel is found to behave
essentially classically: the present quantum-mechanical angular distributions for this
channel are in good agreement with both the earlier quasi-classical trajectory results of Aoiz …
