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: An isomeric 0+ state at E x = 2.24 MeV in 12Be was found in the projectile fragmentation of 18O at 100 A MeV on a Be target as discussed by the authors, where the excitation energy and the spin assignment were deduced by measurements of the energies and the angular correlation function of the coincident two γ-rays corresponding to the 0+ → 2+ → 0+ decay.

TL;DR: In this article, compact liquid hydrogen, deuterium, and helium targets were constructed for radioisotope beam experiments at RIKEN and operated stably in several experiments.
