A-values are from the NIST database. ! Accurate transition frequencies measured by Zink et al. 1991, ! ApJ, 371, L85. ! The full reference for O+H2: Jaquet, R., Staemmler, V., ! Smith, M.D., & Flower, D.R. 1992, J. Phys. B, 25, 285. ! See also Monteiro and Flower (1987, MNRAS, 228, 101) for an ! explanation why the cross sections and rates are surprisingly ! low for the ^3P_0 - ^3P_1 transition. ! Transition frequencies for the 17O and 18O isotopes can be found ! in Brown, Evenson, Zink (1993, Phys. Rev. A, 48, 3761) and in ! DeNatale et al. (1993, Phys. Rev. A, 48, 3757). The latter reference ! presents more precise values. ! UPDATE (2011-6-16): H+O collision cross sections and rates have been ! recomputed with use of more accurate interaction potentials by ! Abrahamsson et al. (2007, ApJ, 654, 1171) and these rates are significantly ! larger than the older rates of Launay and Roueff (1977). Note also that ! Krems et al. (2006, ApJ, 647, 1531) have investigated the H + O(^3P) <-> ! H + O(^1D) process. Even the downward rate coefficients are relatively ! slow; however, the de-excitation process is a means for ! producing kinetically hot H atoms if O(1D) is otherwise ! excited in warm neutral gas. The 1D and 1S states should be included, ! together with some of the UV resonance lines, and extended to higher ! temperature in a future update. John.Black@chalmers.se ! ! OLD DATA: !!
