To investigate the recent report of the observation of a reactive resonance
in the title reaction, we have calculated the ro-vibrationally state-resol
ved integral cross-sections (ICS) and differential cross-sections (DCS), as
well as the vibrational branching ratios for the H + D-2(nu = j = 0) --> H
D(nu',j') + D reaction. Oscillatory structure occurring in the state-to-sta
te reaction probabilities does survive partial wave averaging to appear in
the integral cross-sections for low j'-values, although not significantly f
or the j' = 7 state recently reported. The resonance picture interpretation
of the oscillations is shown to be problematic. (C) 2001 Elsevier Science
