Figure 9
Two-dimensional plots \(d(E\sigma )/dE\) vs \(E\sigma \) (top panel) and \(d[ln(E\sigma )]/dE\) vs \(E\sigma \) (bottom panel) for \(^{26,24}\)Mg + \(^{12}\)C37,38. The top panel reports also the trend of \(^{30}\)Si + \(^{12}\)C39. The line indicated with \(L_{CS}\) marks the logarithmic derivative values corresponding to a constant astrophysical S factor, for different energies (see Ref.23).
