Nuclei with proton and neutron numbers away from stability are known as exotic, and provide stringent tests of nuclear models, mainly developed for the description of stable nuclei. However, only the most extreme combinations lead to literally exotic

International audience; Spectroscopy of an unbound nucleus $^{17}$C was performed using the SAMURAI spectrometer at RIBF of RIKEN. Six resonances were observed for the $^{16}$C+n system with relative energies of 0.52, 0.77, 1.36, 1.91, 2.22 and 3.20

We review an extensive study of the beryllium isotopic chain carried out at RIKEN. In particular, we discuss the results on $$^{13,15}\hbox {Be}$$ , two key isotopes for the understanding of dineutron configurations and decays in $$^{14,16}\hbox {Be}

The quest for light multineutron systems

European Physical Journal A, EDP Sciences, 2021, 57 (3), pp.105. ⟨10.1140/epja/s10050-021-00417-8⟩

The long history of the research concerning the possible existence of bound or resonant states in light multineutron systems, essentially $^3$n and $^4$n, is reviewed. Both the experimental and the theoretical points of view have been considered, wit

We consider the evolution of the neutron-nucleus scattering length for the lightest nuclei. We show that, when increasing the number of neutrons in the target nucleus, the strong Pauli repulsion is weakened and the balance with the attractive nucleon

Modeling B19 as a B17−n−n three-body system in the unitary limit

Autor: Emiko Hiyama, Rimantas Lazauskas, F. Miguel Marqués, J. Carbonell

Publikováno v: Physical Review C. 100

We present a model description of the bound $^{19}\mathrm{B}$ isotope in terms of a $^{17}\mathrm{B}\ensuremath{-}n\ensuremath{-}n$ three-body system where the two-body subsystems $^{17}\mathrm{B}\ensuremath{-}n$ and $n\ensuremath{-}n$ are unbound (v
