DREB2014 - Direct Reactions with Exotic Beams

We report on an exploratory experiment performed with MINIBALL coupled to T-REX [1-2] at ISOLDE, to investigate neutron rich Sr and Y nuclei around mass A = 100, by cluster transfer reactions of neutron rich 98Rb/98Sr beams on a 7Li target. The aim of the experiment was on one hand to perform a γ-spectroscopy study by transfer reactions of neutron-rich Sr and Y nuclei beyond N=60 populated, so...

Nuclear break-up occurring at few tens of MeV per nucleon is an efficient tool to study clusterization into nuclei. A landscape of information extracted through nuclear break-up will be given. Firstly, pairing correlations can be studied. Pairing plays an important role to understand various aspect of nuclear physics but also nuclear astrophysics. Halo nuclei are the best place to study...

Many theoretical and experimental studies have been devoted to the cluster structure in nuclei in the past decades. But the detailed mechanism of clustering in nuclei is still an open question and is of fundamental importance in nuclear physics. For stable nuclei, the cluster structure is generally developed at excited states close to the corresponding particle decay threshold as illustrated...

How important is the three-nucleon force (3NF)? This is one of the fundamental subjects in nuclear physics. This long-standing subject essentially started with the two-pion exchange 3NF proposed by Fujita and Miyazawa. For light nuclei, attractive 3NFs were introduced to reproduce the binding energies. In symmetric nuclear matter, the empirical saturation point could not be reproduced only...
