State-selected reaction probabilities for the collinear reaction He+H~-(v)~HeH++H have been computed for v = 0-4 over a wide range of energies (to the dissociation limit), using the time-dependent wavepacket approach via time-energy mapping of the reactive flux. The results reproduce quantitatively

โฆ Synopsis
The Distorted Wave Born Approximation (DWBA) is used to study the reaction prcbability in the threshold region for the collinear H + Hz rezc:ion. 'lk eft'ect of varying the features of the distortion surface upon the reaction probability is investigated. It is found that n fair approximation to cwct reaction probabilities already reported for this reaction may be obtained fix a suitable choice of distortion surface parameters. The DWBA results provide a significant improvement over the predictions of clnssical mechanics in the threshold region.
