Spin-dependent effective interactions for halo nuclei
We discuss the spin dependence of the effective two-body interactions appropriate for three-body computations. The only reasonable choice seems to be the fine and hyperfine interactions known for atomic electrons interacting with the nucleus. One exception is the nucleon-nucleon interaction imposing a different type of symmetry. We use the two-neutron halo nucleus Li as an illustration. We demo...

متن کاملSizes and interactions of halo nuclei
Abstract Theories of reactions of composite nuclei simplify considerably at energies of several 100 MeV/nucleon. Here Glauber methods provide a quantitative microscopic framework with a clear delineation of nucleon-nucleon scattering and nuclear structure inputs. However further approximations, tested for stable nuclei, are inappropriate for few-body halo nuclei with implications for analyses o...
متن کاملHelium halo nuclei from low-momentum interactions
We present ground-state energies of helium halo nuclei based on chiral low-momentum interactions, using the hyperspherical-harmonics method for He and coupled-cluster theory for He, with correct asymptotics for the extended halo structure.
متن کاملRealistic Effective Interactions and Nuclear Structure Calculations
We address the two main questions relevant to microscopic nuclear structure calculations starting from a free NN potential. These concern the accuracy of these kinds of calculations and the extent to which they depend on the potential used as input. Regarding the first question, we present some results obtained for nuclei around doubly magic Sn and Pb by making use of an effective interaction d...
