Abstract

We solve the ab initio no-core shell model (NCSM) in the complete 8\ensuremathℏ\ensuremathΩ (N_max=8) basis for A=7 and A=8 nuclei with two-nucleon and three-nucleon interactions derived within chiral effective field theory (EFT). We find that including the chiral EFT three-nucleon interaction in the Hamiltonian improves overall agreement with experimental binding energies, excitation spectra, transitions, and electromagnetic moments. We predict states that exhibit sensitivity to including the chiral EFT three-nucleon interaction but are not yet known experimentally.
