LSTH potential energy parameters trajectory calculation

LSTH potential energy parameters non-adiabatic coupling, quasiclassical trajectory (QCT) calculation ... 

The other data are from quasiclassical trajectory calculations by Mayne and Toennies. Again, all of the calculations use the LSTH potential the results are shown in Fig. 3. To search for the threshold we made special runs for rel " °. 28 eV, one with a very small impact parameter, 0.3 uq the top of the error bar at that energy in Fig. 3 indicates the value that would have been calculated for the cross section if only one of the trajectories had reacted.
