(JAEA, Ibaraki) et al.
Detailed $\gamma$-ray spectroscopy of the exotic neon isotope $^{28}$Ne has been performed for the first time using the one-neutron removal reaction from $^{29}$Ne on a liquid hydrogen target at 240~MeV/nucleon. Based on an analysis of parallel momentum distributions, a level scheme with spin-parity assignments has been constructed for $^{28}$Ne and the negative-parity states are identified for the first time.

Presently under construction in Lund, Sweden, the European Spallation Source (ESS) will be the world's brightest neutron source. As such, it has the potential for a particle physics program with a unique reach and which is complementary to that available at other facilities. [...]

Beta decay is a primary source of information of the structure of a nucleus. An accurate measurement of the half-life of a nucleus is essential for the proper determination of the reduced Gammow–Teller transition probability $B$(GT) [...]

The experiments to determine the electron capture and $\beta$-decay of $^8$B into the highly excited states of $^8$Be
/ Vinals, S (Madrid, Inst. Estructura Materia) ; Borge, M J G (Madrid, Inst. Estructura Materia) ; Tengblad, O (Madrid, Inst. Estructura Materia) ; Nacher, E (Valencia U., IFIC) ; Benito, J (UCM, Madrid, Dept. Phys.) ; Figuera, P (INFN, Catania) ; Fraile, L M (UCM, Madrid, Dept. Phys.) ; Fynbo, H O U (Aarhus U.) ; Gad, A (Aarhus U.) ; Jensen, J (Aarhus U.) et al.
The main goal of this work is to study the structure of the highest energy states in $^8$Be populated following the $\beta^+$-decay and the electron capture (EC) of $^8$B. With this aim, two experiments were performed at ISOLDE-CERN in 2017 and 2018. [...]

We report on an attempt to reproduce the observation of $\beta^-$-delayed proton emission from $^{11}$Be through detection of the final state nucleus $^{10}$Be with accelerator mass spectrometry. Twelve samples were collected at the ISOLDE facility at CERN at different separator settings, allowing tests of different sources of contamination to be carried out. [...]

Chronology of the three-body dissociation of $^8$He
/ Laurent, B. (Caen U.) ; Marqués, F.M. (Caen U.) ; Angulo, C. (Cathol. U. Louvain (main)) ; Ashwood, N.I. (Birmingham U.) ; Borge, M.J.G. (CSIC, Madrid) ; Bouchat, V. (U. Brussels (main)) ; Catford, W.N. ; Clarke, N.M. (Birmingham U.) ; Curtis, N. (Birmingham U.) ; Freer, M. (Birmingham U.) et al.
The space and time configurations of the dissociation of $^8$He into $^6$He+$n$+$n$, on C and Pb targets, have been explored simultaneously for the first time. The final-state interactions in the $n$-$n$ and $^6$He-$n$ channels are successfully described within a model that considers independent emission of neutrons from a Gaussian volume with a given lifetime.

The progress within atomic and nuclear physics relies on refining and adding new observables. One of these is the polarization of the nuclear spin, where there is a manifest interest in accessing a wide variety of polarized beams, e.g. [...]

Study of bound states in $^{10}Be$ by one neutron removal reactions of $^{11}Be$

The bound states of (10)Be have been studied by removing single neutrons from $^{11}Be$ nuclei. A 2.8 MeV $u^{–1}$ beam of $^{11}Be$was produced at ISOLDE, CERN and directed on to both proton and deuteron targets inducing one-neutron removal reactions. [...]
