Findings

Ground state energies for $^4$He, $^{12}$C, and $^{14}$F are obtained.

$^{12}$C is overbound by 1.7 MeV.

Predicted binding energy of $^{14}$F is $70.2 extpm 3.5$ MeV.

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 $70.2\pm 3.5$ MeV. The extrapolated spectrum of $^{14}$F is in reasonable agreement with known features of the $^{14}$B spectrum.
