Recent experimental results on Coulomb and nuclear breakup for neutron drip-line nuclei at the newly commissioned RIBF at RIKEN are presented. Coulomb breakup reaction is a useful tool to probe halo structure since the cross section is enhanced due to the large E1 transitions at low excitation energies (soft E1 excitation) for halo nuclei. We have measured inclusive Coulomb breakup cross...

The "Island of inversion" is a region in the nuclear chart around the neutron rich N=20 isotopes of Ne, Na and Mg, where intruder fp-orbitals favoring deformed shapes compete with the normal spherical sd configurations.
Transfer reactions yield important spectroscopic information, i.e. spin and parity assignments as well as spectroscopic factors, complementary to the information obtained...

For the $^{28,29,30}$Na isotopes a gradual transition from the usual filling of the neutron levels into the region with low lying 2p-2h cross shell configurations, the so-called island of inversion, is described by theory [1,2]. Detailed theoretical predictions for the transition strength are awaiting experimental verification in all three Na nuclei. Collective properties of excited states of...

The nuclear charge radius is a critical probe for testing nuclear models and detecting anomalies in the nuclear structure. The isotopic chain of magnesium exhibits intruder configurations with the pf shell being populated before the sd shell is complete. In this “island of inversion” the nuclear charge radii would indicate this structural change, expected to happen in the step from 30Mg to...
