FIG. 2.

(Color) Reaction probabilities for the reaction and as a function of collision energy, , obtained with the different theoretical methods employed in this work (top panel). EQM result is in black, QWP probability is in green, the SQM result is in blue, and the QCT result is in red. At the bottom panel, the same comparison is shown with the EQM and QWP probabilities smoothed by means of an energy convolution with a Gaussian function.
