Abstract

We construct effective two- and three-body Hamiltonians for the p-shell by performing 12 Ω ab initio no-core shell model (NCSM) calculations for A=6 and 7 nuclei and explicitly projecting the many-body Hamiltonians onto the 0 Ω space. We then separate these effective Hamiltonians into inert core, one- and two-body contributions (also three-body for A=7) and analyze the systematic behavior of these different parts as a function of the mass number A and size of the NCSM basis space. The role of effective three- and higher-body interactions for A>6 is investigated and discussed.
