| Résumé : | We present a brief overview of scattering models at low energies. We first discuss the simple potential model, where the structure of the colliding nuclei is neglected. We develop in more detail the phase-shift method and discuss the choice of the optical potentials. The R-matrix theory is presented as an efficient tool to solve scattering problems, in particular for multichannel systems. We present a short description of the continuum discretized coupled channel (CDCC) theory, where breakup channels in the projectile and/or in the target are taken into account. Finally, we discuss transfer reactions and introduce the distorted wave Born approximation (DWBA). |
