Abstract
Precise fusion and quasi-elastic scattering excitation functions have been measured for the systems View the 40Ca + 90,96Zr source at energies spanning the Coulomb barrier. From both the fusion and the quasi-elastic scattering data representations of the barrier distributions have been extracted. The barrier distributions of the two reactions are qualitatively very different. While the lighter system is well described by coupled-channels calculations including multi-phonon excitations, this coupling scheme fails completely for the heavier system, possibly due to multi-neutron transfer.File in questo prodotto:
