Abstract
We develop a new ab initio many-body approach capable of describing simultaneously both bound and scattering states in light nuclei, by combining the resonating-group method with the use of realistic interactions, and a microscopic and consistent description of the nucleon clusters. This approach preserves translational symmetry and Pauli principle. We present phase shifts for neutron scattering on , , and and proton scattering on , using realistic nucleon-nucleon potentials. Our scattering results are compared to earlier ab initio calculations. We demonstrate that a proper treatment of the coupling to the continuum is successful in explaining the parity-inverted ground state in .
