“…This potential, although simpler than the more sophisticated AV18 [46], CD-Bonn [47] or Reid93 [48] interactions, reproduces NN observables up to 300 MeV, so it is suitable for three-body structure calculations. In order to get a realistic description of 14 Be, the 12 Be-n interactions needs to reproduce the properties of the unbound binary subsystem 13 Be. From previous fragmentation and knockout experiments, it is mostly accepted that 13 Be exhibits a low-lying s-wave state and a d-wave resonance around 2 MeV relative energy [10,11,14].…”
