Figure 6

(top panel) Fusion excitation functions for \(^{58,64}\)Ni + \(^{124}\)Sn28 and for \(^{132}\)Sn + \(^{58,64}\)Ni26,27. The abscissa is the energy with respect to the Akyüz-Winther Coulomb barrier. This panel is adapted from Ref.4. (bottom panel) Representation of \(d(E\sigma )/dE\) vs \(E\sigma \) for the same systems.
