We report a comprehensive study of 1014B isotopes within the ab-initio no-core shell model (NCSM) using realistic nucleon-nucleon (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 (N3LO) and optimized next-to-next-to-leading order (N2LOopt) interactions are also reported. We have reached basis sizes up to Nmax = 10 for 10B, Nmax = 8 for 11,12,13B and Nmax = 6 for 14B 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 ab-initio nuclear theory. Overall, our NCSM results are consistent with the available experimental data. The experimental ground state spin 3+ of 10B has been reproduced using the INOY NN interaction. Typically, the 3N interaction is required to correctly reproduce the aforementioned state.

具有现实NN相互作用的10−14B同位素的Ab-Initiono核壳模型研究

我们报告了对 10-14从头开始的无核壳模型(NCSM)中的B同位素,使用现实的核子-核子(NN)相互作用。尤其是,我们已应用内部非局部外部Yukawa(INOY)相互作用来研究硼同位素的能谱,电磁特性和点质子半径。NCSM的结果取决于电荷相关的Bonn 2000(CDB2K),即手性的从前到下一到从前到前的顺序(N3LO)和优化的倒数第二个前导顺序(N2LOØpŤ)的互动也有报道。我们的基本规模已达到ñ最高 = 10 10B, ñ最高 = 8 111213B和 ñ最高 = 6 14B的m方案规模高达17亿。我们还使用壳模型将NCSM计算与现象学YSOX交互作用进行了比较,以检验从头算核理论的预测能力。总体而言,我们的NCSM结果与可用的实验数据一致。实验性基态自旋3+10B已使用INOY NN交互复制。通常,需要3N交互才能正确重现上述状态。
