论文摘要
我们使用现实的核素 - 核子（\ textIt {nn}）交互作用，报告了\ textIt {ab-initio}内的$^{10-14} $ b同位素的综合研究。特别是，我们已在Yukawa（Inoy）相互作用以外的内部非本地进行了研究，以研究硼同位素同位素的能量光谱，电磁特性和点proton半径。 NCSM的结果与电荷有关的BONN 2000（CDB2K），手性近代到次要到领先的顺序（n $^3 $ lo），还报告了近代到领先的订单（N $^2 $ lo $ $ $ _ {OPT} $）的相互作用。我们已经达到了最高$ n _ {\ mbox {max}} $ = 10的$ n _ {10} $ b，$ n _ {\ mbox {max}} $ = 8 for $^for $^{11,12,12,13} $ b and $ n _ _ {\ mbox {\ mbox {\ mbox {\ mbox} 17亿。我们还使用壳模型将NCSM计算与现象学YSOX相互作用进行了比较，以测试\ textit {ab-initio}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。 $^{10} $ b的实验基态自旋$ 3^{+} $已使用Inoy \ textit {nn}相互作用复制。通常，需要3 \ textit {n}交互才能正确重现上述状态。
We report a comprehensive study of $^{10-14}$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 (N$^3$LO) and optimized next-to-next-to-leading order (N$^2$LO$_{opt}$) interactions are also reported. We have reached basis sizes up to $N_{\mbox{max}}$ = 10 for $^{10}$B, $N_{\mbox{max}}$ = 8 for $^{11,12,13}$B and $N_{\mbox{max}}$ = 6 for $^{14}$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 $3^{+}$ of $^{10}$B has been reproduced using the INOY \textit{NN} interaction. Typically, the 3\textit{N} interaction is required to correctly reproduce the aforementioned state.
