AI 中文摘要
我们首次将Efros方法应用于散射问题的从头算多体计算,该方法利用连续谱波函数的简谐子展开。我们选取单道nα散射,采用无芯壳模型(NCSM)计算得到的低能本征态,获得了收敛性良好的散射结果,与实验结果吻合合理。这些结果表明Efros方法计算上切实可行,有望进一步应用于核反应的从头算多体研究。
英文摘要
We present the first $\textit{ab initio}$ many-body application of the Efros method for scattering utilizing the harmonic oscillator expansion of the continuum wave function. We select single-channel $nα$ scattering and, using low-lying eigenstates from no-core shell model (NCSM) calculations, we obtain well-converged scattering results that are in reasonable agreement with experiment. The results demonstrate that the Efros method is computationally practical and promising for further $\textit{ab initio}$ many-body studies of nuclear reactions.
