Full configuration interaction calculations of light nuclei*

We perform full configuration interaction (FCI) calculations for light nuclei with a realistic NN interaction, JISP16. We obtain ground state energies and their uncertainties through an exponential extrapolation that we demonstrate is reliable in testcases up to A=4 where fully converged results are obtained. For heavier nuclei, up through Carbon-12, we obtain ground state energies converged to a few percent. In addition to the energies, we also calculate selected observables such as rms radii and quadrupole moments.
