我们从手性二核子和三核子力推导出核子-核子散射的微观光学势。光势的实中心项和虚中心项是由给定密度和同位旋不对称的无限核物质中的核子自能得到的,在多体摄动理论中自洽地计算到二阶。利用改进的密度矩阵展开,从相同的手性势中提取出实际的自旋轨道项。然后将与密度相关的光势与核密度分布折叠在一起,利用核密度分布我们研究了质子-核弹性散射和使用反应代码计算的总反应截面。我们将微观计算结果与现象学模型和实验数据的结果进行了比较,直至mev的弹丸能量。虽然得到了与现有实验数据总体上令人满意的一致性,但我们发现,当虚光势较弱时,特别是当弹丸能量较大时,弹性散射和总反应截面可以得到显著改善。
We formulate microscopic optical potentials for nucleon-nucleus scattering from chiral two- and three-nucleon forces. The real and imaginary central terms of the optical potentials are obtained from the nucleon self-energy in infinite nuclear matter at a given density and isospin asymmetry, calculated self-consistently to second order in many-body perturbation theory. The real spin-orbit term is extracted from the same chiral potential using an improved density matrix expansion. The density-dependent optical potential is then folded with the nuclear density distributions offrom which we study proton-nucleus elastic scattering and total reaction cross sections using the reaction codetalys. We compare the results of the microscopic calculations to those of phenomenological models and experimental data up to projectile energies ofMeV. While overall satisfactory agreement with the available experimental data is obtained, we find that the elastic scattering and total reaction cross sections can be significantly improved with a weaker imaginary optical potential, particularly for larger projectile energies.
