论文摘要
我们使用基于手性有效田间理论的双重折叠方法来确定光电位，在近代到领先的顺序上结合分散关系以限制假想部分。此方法在$^{16} $ o - $^{16} $ o碰撞上进行基准标记，并扩展到$^{12} $ c - $^{12} $ c和$^{12} $ c - $ c - $^{16} $ o case。将这些电势得出的预测与高达1000 MeV的能量的弹性散射以及低能融合的数据进行了比较。在不调整参数的情况下，可以找到与实验的良好一致性。此外，我们研究了相应的横截面对所使用的核子核子相互作用和核密度的敏感性。
We present a determination of optical potentials using the double-folding method based on chiral effective field theory nucleon-nucleon interactions at next-to-next-to-leading order combined with dispersion relations to constrain the imaginary part. This approach is benchmarked on $^{16}$O--$^{16}$O collisions, and extended to the $^{12}$C--$^{12}$C and $^{12}$C--$^{16}$O cases. Predictions derived from these potentials are compared to data for elastic scattering at energies up to 1000 MeV, as well as for fusion at low energy. Without adjusting parameters, excellent agreement with experiment is found. In addition, we study the sensitivity of the corresponding cross sections to the nucleon-nucleon interactions and nuclear densities used.
