Ab-Initio Shell Model with a Core

Description

We construct effective 2- and 3-body Hamiltonians for the p-shell by performing 12(hbar)(Omega) ab initio no-core shell model (NCSM) calculations for A=6 and 7 nuclei and explicitly projecting the many-body Hamiltonians onto the 0(hbar)(Omega) space. We then separate these effective Hamiltonians into 0-, 1- and 2-body contributions (also 3-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 3- and higher-body interactions for A > 6 is investigated and discussed
