For j=0 initial state, reaction probabilities for all the partial waves have been
calculated explicitly, while for j=1-2 initial states, only the probabilities for J[0,10]
and J=15,20,25,…,95, (every five J) and 99 are calculated explicitly. The probabilities
for missing Js are obtained via interpolation over J space to calculate integral cross
sections and rate constants.
In this supplementary material, we demonstrate the accuracy of the interpolation
performed over J space. For j=0 initial state, assuming only probabilities for limited
number of Js (the same set of Js as j>0) are available, the probabilities for other
missing Js are obtained via interpolation. The interpolated results are compared with
the exactly calculated ones.
The interpolated results are compared with the exact ones in Fig. 1, 2, and 3 for
J=12 probabilities, integral cross sections, and rate constants respectively. As these
figures show the agreement between the two is excellent, reproducing even the slight
structures shown in Fig. 1 and 2 by the interpolation method.
