Generalized extrapolation method for excitation energies

Validation of techniques with mirror nucleus $^{14}$B

Abstract

We present results from ab initio No-Core Full Configuration simulations of the exotic proton-rich nucleus $^{14}$F whose first experimental observation is expected soon. The calculations with JISP16 NN interaction are performed up to the $N_{\max}=8$ basis space. The binding energy is evaluated using an extrapolation technique. This technique is generalized to excitation energies, verified in calculations of $^6$Li and applied to $^{14}$B, the $^{14}$F mirror, for which some data are available.
