“…The ratio of the same data set to the absolute best solution (ABF) with radius R = 2.28 fm is shown by the solid (red) points. Also shown at higher energies is the ratio of Charvet's data [3] to the same solution (with radius R = 2.28 fm.) It is seen that the ratios for the absolute best solution are essentially constants (≈ 0.84 for Trentalange's data, and ≈ 0.92 for Chatvet's data up to 10 MeV).…”

The coupled-channels calculations include 26 channels and are based on the M3Y+repulsion potential using the 13 C radius R = 2.17 fm (BF, Sc=1) and R=2.28 fm (ABF, Sc=0.843), respectively.

“…The calculated cross sections defined this way are fairly smooth as functions of the center-of-mass energy and they are well suited to analyze the fusion data for 13 C+ 13 C [2,3] and 12 C+ 13 C [4,5]. The 12 C+ 12 C fusion data, on the other hand, contain a lot of structures or resonances, and it is beyond the scope of this investigation to try to reproduce these data in detail.…”

Fusion data for 13 C+ 13 C, 12 C+ 13 C and 12 C+ 12 C are analyzed by coupled-channels calculations that are based on the M3Y+repulsion, double-folding potential. The fusion is determined by ingoingwave-boundary conditions (IWBC) that are imposed at the minimum of the pocket in the entrance channel potential. Quadrupole and octupole transitions to low-lying states in projectile and target are included in the calculations, as well as mutual excitations of these states. The effect of oneneutron transfer is also considered but the effect is small in the measured energy regime. It is shown that mutual excitations to high-lying states play a very important role in developing a comprehensive and consistent description of the measurements. Thus the shapes of the calculated cross sections for 12 C+ 13 C and 13 C+ 13 C are in good agreement with the data. The fusion cross sections for 12 C+ 12 C determined by the IWBC are generally larger than the measured cross sections but they are consistent with the maxima of some of the observed peak cross sections. They are therefore expected to provide an upper limit for the extrapolation into the low-energy regime of interest to astrophysics.
