FIG. 1.

Threshold behavior of the reagent helicity states (labeled by ) for computed using converged quantum scattering theory. The backward scattered DCS’s, , are plotted vs total energy for all initial states with and . Each curve has been a multiplied by constant scaling factor to facilitate comparison. It is seen that the reaction threshold is completely governed by the value of , and is nearly independent of . We find that the -value of the reagent merely determines the scaling factor and is proportional to the formation probability of the ground QBS for the various reagent initial states.

FIG. 2.

Rotational product distribution of the reagent helicity states (labeled by ) for computed using converged quantum scattering theory. The backward scattering DCS for all initial states with , and 2 and are plotted at several total energies. Each distribution is multiplied by a -independent scaling factor to facilitate comparison. It is seen that states with the same initial -quantum number yield distributions that are nearly proportional for low energy.

FIG. 3.

The backward scattering DCS for the and oriented reagent states of at a series of total energies, . The exact quantum scattering results are shown with solid lines and predictions of Eq. (2) are shown with dashed lines.

FIG. 4.

The backward scattered DCS for . The experimental results, shown with symbols, are obtained from unpolarized molecular beam experiments using Eq. (2) to infer the helicity selected DCS. The expected results, based on converged quantum scattering calculations, is shown for reference.
