Abstract

We introduce the no-core full configuration (NCFC) approach and present results for $^4$ He, $^{12}$ C and $^{14}$ F with the realistic NN interaction, JISP16. We obtain ground state energies and their uncertainties through exponential extrapolations that we demonstrate are reliable in $^4$ He where fully converged results are obtained. We find $^{12}$ C is overbound by 1.7 MeV and we predict the yet-to-be-measured binding energy of $^{14}$ F to be $68.1 \pm 2.7$ MeV. The extrapolated spectrum of $^{14}$ F is in reasonable agreement with known features of the $^{14}$ B spectrum.
