英文摘要 | The h+h-2 reaction is the simplest chemical reaction system and has long been the prototype model in the study of reaction dynamics. here we report a high resolution experimental investigation of the state-to-state reaction dynamics in the h+hd -> h-2+d reaction by using the crossed molecular beams method and velocity map ion imaging technique at the collision energy of 1.17 ev. d atom products in this reaction were probed by the near threshold 1+1'(vacuum ultraviolet+ultraviolet) laser ionization scheme. the ion image with both high angular and energy resolution were acquired. state-to-state differential cross sections was accurately derived. fast forward scattering oscillations, relating with interference effects in the scattering process, were clearly observed for h-2 products at h-2(v'=0, j'=1) and h-2(v'=0, j'=3) rovibrational levels. this study further demonstrates the importance of measuring high-resolution differential cross sections in the study of state-to-state reaction dynamics in the gas phase. |
