Ab Initio Many-Body Calculations of Nucleon-Nucleus Scattering

摘要

The development of an ab initio theory of low-energy nuclear reactions on light nuclei is key to further refining our understanding of the fundamental nuclear interactions among the constituent nucleons and providing, at the same time, accurate predictions of crucial reaction rates for nuclear astrophysics. However, ab initio calculations for scattering processes involving more than four nucleons overall are challenging and still a rare exception (1). Recently we combined the resonating-group method (RGM) (2) and the ab initio no-core shell model (NCSM) (3), into a new many-body approach (4) (ab initio NCSM/RGM) capable of treating bound and scattering states of light nuclei in a unified formalism, starting from the fundamental inter-nucleon interactions.
