Inelastic scattering matrix elements, cross sections and rate constants for transition B(2P1/2)+H2(j=0)⇆B(2P3/2)+H2(j=0)

The non-adiabatic wave packet collisions of B(P-2(1/2)) + H-2(j = 0) <-> B(P-2(3/2)) + H-2(j = 0) were calculated using the time dependent Channel Packet Method to compute transition probabilities, cross sections and rate constants. While the H2 angular momentum j was fixed to 0, the total angular momentum of the system J, was varied from 1/2 to 153/2. The feature of the Stuckelberg oscillation was shown in transition probabilities. The transition from B(P-2(3/2)) to B(P-2(1/2)) state was shown to be favored over the reverse process. The ratio of the computed rate constants was well compared with that of the analytic result obtained from the Boltzmann factor and the detailed balance. Published by Elsevier B.V.
