Title: Ab Initio Nuclear Structure Calculations of Light Nuclei

Abstract

We perform no-core configuration interaction calculations for nuclei in the p-shell. We show that for typical light nuclei, a truncation on the total number of quanta in the many-body system converges much more rapidly than a full configuration interaction (FCI) truncation, which is a truncation on the single-particle basis space. We present new results for the ground state energies of the Be isotopes with the nonlocal two-body potential JISP16, and discuss emerging phenomena such as clustering and rotational band structures in 9Be. We also show that the anomalously suppressed beta decay of 14C to the ground state of 14N can be reproduced using two- and three-nucleon forces from chiral effective field theory. In particular the structure of the ground state of 14N is sensitive to the three-nucleon force.
