Recent developments in quasi-elastic scattering around the Coulomb barrier
نویسنده
چکیده
We discuss two recent topics on heavy-ion quasi-elastic scattering at energies around the Coulomb barrier. The first topic is an application of quasi-elastic scattering at deep-subbarrier energies to extracting the surface diffuseness parameter of the nucleus-nucleus potential. The second topic is a coupled-channels analysis for the quasi-elastic barrier distribution for the 70Zn + 208Pb reaction. We show that the coupled-channels calculations which include the multi-phonon excitations in the colliding nuclei reproduce reasonably well the experimental excitation function for quasi-elastic scattering at backward angles and the barrier distribution for this reaction.

Large-angle scattering and quasi-elastic barrier distributions
We study in detail the barrier distributions extracted from large-angle quasi-elastic scattering of heavy ions at energies near the Coulomb barrier. Using a closed-form expression for scattering from a single barrier, we compare the quasi-elastic barrier distribution with the corresponding test function for fusion. We examine the isocentrifugal approximation in coupled-channels calculations of ...
متن کاملProbing internucleus potential with large-angle quasi-elastic scattering
Recent measurements for fusion cross section at energies around the Coulomb barrier have systematically indicated a significant deviation of fusion cross sections from a prediction of double-folding model. It has been argued that the deviation can be accounted for if one uses a large value of surface diffuseness parameter for a Woods-Saxon internuclear potential. We investigate this problem usi...
متن کاملSurface diffuseness anomaly in heavy-ion potentials for large-angle quasielastic scattering
Recent high precision experimental data for heavy-ion fusion reactions at subbarrier energies systematically show that a surprisingly large surface diffuseness parameter for a Woods-Saxon potential is required in order to fit the data. We point out that experimental data for quasi-elastic scattering at backward angles also favor a similar large value of surface diffuseness parameter. Consequent...
متن کاملElastic scattering and heavy residue production in the collisions 6 , 7 Li + 64 Zn around the Coulomb barrier
Elastic scattering angular distributions and heavy residue production cross sections have been measured at different energies around the Coulomb barrier for the systems Li+Zn. Optical model fits of the elastic angular distributions were performed using a renormalized double folding potential and absence of usual threshold anomaly in the optical potential was found. Excitation functions for heav...
متن کاملElastic scattering and heavy residue production in the collisions Li+Zn around the Coulomb barrier
The study of nuclear collisions involving halo or, more in general, weakly bound nuclei at energies around the Coulomb barrier had a considerable interest in the last decade, since the peculiar structure of the colliding nuclei can deeply affect the reaction mechanisms (see e.g. [1–3] and refs. therein). We measured elastic scattering angular distributions and heavy residue production cross sec...
