DREB2014 - Direct Reactions with Exotic Beams

Most theoretical calculations of direct reactions involving halo nuclei rely on a model of inert core + valence nucleons. However, the internal degrees of freedom of the core may play an important role in the reactions. For inelastic and transfer reactions this has been demonstrated recently in [1] using the framework of exact Faddeev-type equations. This study is being extended to...

Deuteron-induced reactions are being used to produce medical radioisotopes [1] and as surrogates to other reactions (see review [2] and references therein), among their recent applications. Although they have been studied for decades [3-6], the complexity of these reactions continues to make their theoretical description challenging. The direct reaction mechanism is a major contributor to the...

The structure of nuclei in the Z ~ 40, N ~ 60 mass region is perhaps best characterized by the sudden onset of deformation seen in the transition from N=58-60 [1]. This sudden onset of deformation can lead to both spherical and deformed gaps near the Fermi energy level for the same combination of nucleon numbers. The distance of the gaps allows a nucleus to have a coexistence of shapes, as has...

The recent improvements in the experimental sensitivity have opened new avenues to study very neutron-rich isotopes of Carbon and Oxygen, allowing for an improved understanding of the structure of them. The present work aims at exploration of neutron- unbound states of 19C via a one neutron knockout reaction. A study of 19C utilizing in-beam γ-ray spectroscopy measurement reported that the...
