โฆ Synopsis
A fully converged close coupling study is performed of the collinear (I?+ Hz) system on the lowest potential energy surkce.
The surface is derived by the DiMZO (diatomic in molecules-zero overlap) method. Transition probabilities for the reactions: I$ + Hz iv'= 0; 1) + H:! (v') + H+; Y' '= 0,. . ., 7 are given for a number of total energies in the range from 1 eV to 3 eV. It is found that for this energy region the transition v = 0 -v' = 0 is the most preferential. This fact leads us to believe that addition of the upper surface will hove a minor effect on the calculated probabilities of transitions from v = 0 in the above-mentioned en&y range.
