Light nuclei without a core
Abstract
We introduce the no-core full configuration (NCFC) approach and present results for 4He, 12C and 14F with the realistic NN interaction, JISP16. We obtain ground state energies and their uncertainties through exponential extrapolations that we demonstrate are reliable in 4He where fully converged results are obtained. We find 12C is overbound by 1.7 MeV and we predict the yet-to-be-measured binding energy of 14F to be 68.1 2.7 MeV. The extrapolated spectrum of 14F is in reasonable agreement with known features of the 14B spectrum.
