DREB2014 - Direct Reactions with Exotic Beams

The investigation of neutron-rich dripline nuclei, including in particular those exhibiting haloes, is a central theme of present day nuclear structure physics. These studies have, however, been limited for the most part to the He, Li and Be isotopes. With the advent of the RIKEN RIBF and intense energetic beams of 48Ca, the way is now open to explore the structure of heavier neutron dripline...

Two-neutron halo nuclei have exotic structure in their ground states. Theoretically, their structure and binding mechanisms have been studied based on the core+n+n three-body model. From the three-body model calculation, the dineutron correlation, which is characterized as the spatially-correlated neutron pair, has been suggested in the ground states. In this work, we investigate the...

During the past several tens of years, our knowledges about the features of exotic nuclei have been much enhanced. In 1980s, neutron halo structure of neutron drip-line nucleus, which is one of the most notable abnormal features of exotic nuclei, have been found. In 1990s, the vanishing of the N = 20 magic number for neutrons have been more extensively studied and discussed in so-called...

Recent measurements of low-energy (quasi)elastic-scattering angular distribution of halo nuclei have shown a strong suppression of the Coulomb-nuclear interference peak [1]. Examining the components of the elastic-scattering differential cross sections for 11Be + 64Zn and 6He + 208Pb at energies near the Coulomb barrier [2], this appears to be caused by a dramatic phase-change (destructive) of...
