英文摘要: The state-to-state dynamics of the H*(n) + HD -> D*(n') + H-2 reactive scattering at the collision energy of 0.5 eV have been carried out for the first time by using H-atom Rydberg tagging time-of-flight technique. Experimental results show that the angular distribution of the total H-2 products presents clearly forward-backward asymmetric, which considerably differs from that of the corresponding H+ + HD -> D+ + H-2 reaction predicted by previously theoretical calculations. Such disagreement between these two processes suggests that the Fermi independent-collider model is also not valid in describing the dynamics of isotopic variants of the H* + H-2 reaction. The rotational state distribution of the H-2 products demonstrates a saw-toothed distribution with odd-j' > even-j'. This interesting observation is strongly influenced by nuclear spin statistics.
