Energy and angular momentum control of the specific opacity functions in the Ba+HI→BaI+H reaction

摘要: Crossed‐beam and beam‐gas experiments on the reaction Ba+HI→BaI+H have been performed, in which most probable collision energy ranges from 3 to 17 kcal/mol. The results, combined with previous experimental studies this system, show a remarkable dependence. Between low high energies, transition occurs intensity, width, peak location of product vibrational rotational population distributions. onset is estimated occur at approximately 5 For energies smaller than kcal/mol, distribution bell shaped peaks v=12. larger second maximum appears v=0 distribution. distributions crossed‐beam are extremely narrow but broaden lower energies. As increased above BaI excitation very near energetic limit, t...
