Ab Initio Many-Body Calculations of n-3H, n-4He, p-{3,4}He, and n-10Be Scattering

Understand

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 3H, 4He and 10Be and proton scattering on {3,4}He, using realistic nucleon-nucleon potentials.
• Our A=4 scattering results are compared to earlier ab initio calculations.
