Abstract

We report a comprehensive study of 1014^{10-14}B isotopes within the \textit{ab-initio} no-core shell model (NCSM) using realistic nucleon-nucleon (\textit{NN}) interactions. In particular, we have applied the inside non-local outside Yukawa (INOY) interaction to study energy spectra, electromagnetic properties and point-proton radii of the boron isotopes. The NCSM results with the charge-dependent Bonn 2000 (CDB2K), the chiral next-to-next-to-next-to-leading order (N3^3LO) and optimized next-to-next-to-leading order (N2^2LOopt_{opt}) interactions are also reported. We have reached basis sizes up to N\mboxmaxN_{\mbox{max}} = 10 for 10^{10}B, N\mboxmaxN_{\mbox{max}} = 8 for 11,12,13^{11,12,13}B and N\mboxmaxN_{\mbox{max}} = 6 for 14^{14}B with m-scheme dimensions up to 1.7 billion. We also compare the NCSM calculations with the phenomenological YSOX interaction using the shell model to test the predictive power of the \textit{ab-initio} nuclear theory. Overall, our NCSM results are consistent with the available experimental data. The experimental ground state spin 3+3^{+} of 10^{10}B has been reproduced using the INOY \textit{NN} interaction. Typically, the 3\textit{N} interaction is required to correctly reproduce the aforementioned state.
