| Résumé : | The 12C+12C and 16O+16O fusion reactions are investigated in a folding model. We use a multichannel approach involving the 12C(0+ 1, 2+, 0+ 2, 3-) states. The 12C densities (including transition densities) are taken from the RGM calculation of Kamimura. For the nucleon-nucleon interaction, we use the DDM3Y density-dependent interaction. Owing to the explicit presence of inelastic channels, the imaginary part of the optical potential only contains a short-range fusion contribution. The S-factor is then virtually insensitive to the precise value, and the model is free of any fitting parameter. From the coupled-channel system, we determine the elastic and fusion cross sections simultaneously. For the 16O+16O fusion cross section, we show preliminary results obtained in a single-channel approximation, where the 16O densities is obtained from an α+12C cluster calculation. |
