Figure 3
(top panel) Experimental fusion excitation functions. (bottom panel) Plot of \(d[ln(E\sigma )]/dE\) (blue dots) and of \(d(E\sigma )/dE\) (red dots) vs \(E\sigma \) for \(^{48}\)Ca, \(^{36}\)S + \(^{48}\)Ca17,18. The right ordinate of this bottom panel is proportional to the s-wave transmission coefficient and the square of the barrier radius. In this figure and the following ones, the reported experimental errors are statistical uncertainties, and most of them are smaller than the data symbols in several cases.
