Pulsed discharge sources of supersonically cooled F radicals have been crossed with supersonically cooled H-2 to study the F(P-2(3/2),P-2(1/2)) + H-2-->HF(v,J) + H reaction under single collision conditions with a collision energy of 1.8(2) kcal/mol. The HF(v,J) product states are probed via direct absorption of a single mode, tunable near IR laser perpendicular to the plane of intersection of the two jet axes. The high spectral resolution (Delta v approximate to 0.0001 cm(-1))permits the quantum state HF(v,J)distribution to be determined with complete resolution of final rovibrational levels. The J-dependent integral cross sections for HF(v=3,J) are compared with exact quantum scattering calculations by Castillo and Manolopoulous on the ground adiabatic potential energy surface of Stark and Werner. Agreement between theory and experiment is quite good for low J (<3) states. However, theory substantially underpredicts the experimental distributions for high J(greater than or equal to 3) states near the energetic cutoff for ground spin orbit state F(P-2(3/2)) atoms, which may indicate the presence of non-adiabatic reaction channels involving spin orbit excited F*(P-2(1/2)) atoms.
