无核轻核

Light nuclei without a core

J. P. Vary, A. M. Shirokov, P. Maris

摘要:

我们介绍了无核心的完整配置(NCFC)的方法和$^4$他,$^{12}$ C和$^{14}$ F与现实的NN的相互作用,JISP 16目前的结果。我们得到基态能量和他们的不确定性,通过指数外推,我们证明是可靠的$^4$他完全收敛的结果。我们发现$^{12}$ C的过束缚为1.7 MeV,我们预测尚未测量的$^{14}$ F的结合能为$68.1 \pm 2.7$ MeV。$^{14}$ F的外推光谱与$^{14}$ B光谱的已知特征合理一致。

英文摘要:

We introduce the no-core full configuration (NCFC) approach and present results for $^4$He, $^{12}$C and $^{14}$F with the realistic NN interaction, JISP16. We obtain ground state energies and their uncertainties through exponential extrapolations that we demonstrate are reliable in $^4$He where fully converged results are obtained. We find $^{12}$C is overbound by 1.7 MeV and we predict the yet-to-be-measured binding energy of $^{14}$F to be $68.1 \pm 2.7$ MeV. The extrapolated spectrum of $^{14}$F is in reasonable agreement with known features of the $^{14}$B spectrum.
