Recent developments (since the last review in J. of Physics G by I. Tanihata in 1996 [1]) at
RIB facilities opened possibilities of detailed studies of halo nuclei. New facilities have been …

We review recent studies of the evolution of collective excitations in atomic nuclei far from
the valley of β-stability. Collective degrees of freedom govern essential aspects of nuclear …

An exclusive measurement has been made of the Coulomb dissociation of the two-neutron
halo nucleus Li 11 at 70 MeV/nucleon at RIKEN. Strong low-energy (soft) E 1 excitation is …

We have measured the excitation energy spectrum of the 10Be+ n system in the Coulomb
dissociation of the one-neutron-halo nucleus 11Be on a Pb target at 72A MeV. We have …

A review of evidence on the properties of the A= 11 nuclei, with emphasis on material
leading to information about the structure of the A= 11 systems.

Breakup reactions of the one-neutron halo nucleus Be 11 on lead and carbon targets at
about 70 MeV∕ nucleon have been investigated at RIKEN by measuring the momentum …

The extremely neutron-rich nucleus 19 C has been studied by Coulomb dissociation into 18
C+ n at 67 A MeV. A large E 1 strength of 0.71±0.07 e 2 fm 2 has been observed at low …

The three-body breakup 6 He→ 4 He+ n+ n is studied experimentally, using a secondary 6
He ion beam of 240 MeV/nucleon incident on carbon and lead targets. Integrated cross …

Recent developments of physics of nuclear clustering are discussed. Our discussions are
mostly focussed on structural problems because the characteristic feature of the recent …

Halo states extend over an unusually large space where many of their properties hinge on
the tail of the wave functions. Their levels lie mainly just below the thresholds for neutron …
