Abstract: We report a comprehensive study of B10-14 isotopes within the ab initio no-core shell model (NCSM) using realistic nucleon-nucleon (NN) interactions. In particular, we have applied the inside nonlocal 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 (N3LO), and optimized next-to-next-to-leading order (N2LOopt) interactions are also reported. We have reached basis sizes up to Nmax=10 for B10, Nmax=8 for B11,12,13, and Nmax=6 for B14 with m-scheme dimensions up to 1.7×109. We also compare the NCSM calculations with the phenomenological YSOX interaction using the shell model to test the predictive power of the ab initio nuclear theory. Overall, our NCSM results are consistent with the available experimental data. The experimental ground state spin 3+ of B10 has been reproduced using the INOY NN interaction. Typically, the 3N interaction is required to correctly reproduce the aforementioned state.
