TL;DR: An exclusive measurement has been made of the Coulomb dissociation of the two-neutron halo nucleus 11Li at 70 MeV/nucleon at RIKEN, where strong low-energy E1 excitation is observed, which represents the strongest E1 transition ever observed at such low excitation energies.

TL;DR: The energy of the first excited state of the very neutron-rich nucleus 30 Ne was determined by proton inelastic scattering as mentioned in this paper, indicating enhancement of deformation as the neutron excess increases in the N = 20 isotones.

TL;DR: In this paper, the B(E2;0+g.s.→2+1) value for the previously proposed 2+1 state in 34Mg was determined for the first time to be 631(126) e 2 fm 4.

TL;DR: In this paper, the location of low-lying states in the very neutron-rich isotope 34 Mg has been determined for the first time using a two-step fragmentation reaction, and two strong γ -lines were observed at 660(10) and 1460(20) kV, which are tentatively attributed to the 2 + 1 → 0 + g.s. and 4 + 1→2 + 1 transitions in 34 mg, respectively.

TL;DR: In this article, an experiment to search for very neutron-rich nuclei has been performed at RIKEN, using projectile fragmentation of an intense 64-A-MeV 48Ca beam and the fragment separator RIPS.
