DREB2014 - Direct Reactions with Exotic Beams

Elastic angular distributions of the 6He+120Sn and 6He+58Ni scatterings have been measured at energies slightly above the Coulomb barrier. Three and four-body continuum discretized coupled channels calculations have been performed. For the 6He+58Ni system, the three-body CDCC calculation underestimates the experimental cross sections in the intermediate angles region and the four-body...

Spin asymmetry in direct reactions is rich source of information on nuclear structure, reaction mechanism, and spin-dependent interactions. From more than half century ago, a number of scattering experiments using polarized light ions have been performed at facilities all over the world. Application of such powerful methods to the field of unstable nuclei should enable us to reveal new aspects...

Evolution of collectivity in the vicinity of N=Z has attracted a lot of attention due to the large variety of nuclear shapes manifested in the ground and excited states. Above the doubly magic nucleus 56Ni, collectivity in the 2+->0+ transition gradually increases up to 72Kr along N=Z, which is followed by the rapid enhancement of collectivity toward 76Sr[1] and 80Zn with a significant...

Removal reactions have played a key role in investigating properties of valence nucleons in weakly-bound nuclei such as one- and two-neutron halo nuclei. Spectroscopic factors and orbital angular momenta of valence nucleons in incident nuclei can be deduced from the removal cross sections. To understand such properties of halo nuclei, an accurate analysis for neutron removal reactions is...
