论文摘要
Nucleus-Nucleus光电位是由Brueckner等人首先概述的能量密度功能方法构建的。能量密度功能的相互作用项来自用两体性手性核力量在核物质中计算出的复杂核能自我能源。核密度分布是从限制在用于自我能力的同一手性力量的状态方程的Skyrme功能中计算得出的。将弹性散射截面和融合横截面的预测与实验数据进行了比较。在实验中发现了较重的核核系统的弹性散射在$ 20 <e <e <90 $ meV/n的范围内，而准确的较轻和较低能源系统的准确描述可能需要集体激励。
Nucleus-nucleus optical potentials are constructed from an energy density functional approach first outlined by Brueckner et al. The interaction term of the energy density functional comes from the complex nucleon self-energy computed in nuclear matter with two- and three-body chiral nuclear forces. Nuclear density distributions are calculated from Skyrme functionals constrained to the equations of state calculated from the same chiral forces used for the self-energy. Predictions for elastic scattering cross sections and fusion cross sections are compared to experimental data. Very good agreement is found with experiment for elastic scattering of heavier nucleus-nucleus systems at energies in the range of $20 < E < 90$ MeV/N, while accurate descriptions of lighter and lower-energy systems may require the inclusion of collective excitations.
