Unified studies of the exotic structures in 12Be and the α+8He slow scattering

The α+8He low‐energy reactions and the exotic structures of 12Be are studied using the generalized two‐center cluster (α+α+4N) model. The energy‐spin systematics for the two‐neutron transfer reactions is investigated, and our calculation predicts a sequence of resonant structures in the range of 3–14 MeV in the center‐of‐mass energy with spins 0ℏ–8ℏ.
