Abstract
We perform no-core full configuration calculations for a set of light nuclei including O with a realistic NN interaction, JISP16. We obtain ground state energies and their uncertainties through exponential extrapolations that we demonstrate are reliable in H, H and He test cases where fully converged results are obtained directly. We find that He, Li and He are underbound by about 600 keV, 560 keV and 1.7 MeV, respectively. C is overbound by about 1.7 MeV and O is overbound by about 16 MeV. The first excited states in C and O are also evaluated but their uncertainties are significantly larger than the uncertainties for the ground states.
