英文摘要: The dynamics of the F+H-2(v=0, j=0, 1) reactions have been studied at the collision energy of 1.27 kcal/mol using a high-resolution crossed molecular beam apparatus. HF product rotational state resolved differential cross sections have been obtained at the v'=1, 2, 3 levels. The product HF(v'=2) angular distributions are predominantly backward scattered for both H-2 (j=0, 1) reagents. However, the distributions of product HF(v'=2) rotational states for the F+H-2(v=-0, j=0) reaction are significantly different from those for the F+H-2(v=0, j=1) reaction. Experimental results show that the rotational excitation of H-2 produces rotationally 'hotter' HF(v'=2) product. In addition, the HF(v'=3) product is more likely scattered into the forward direction when the H-2 reagent is populated at j=0 state, which could be attributed to a slow-down mechanism.
