在复矩阵相互作用的双折叠模型框架下，研究了高密度核物质的核-核弹性散射性质。基于冻结密度近似，本文用两种方法研究了包含三体力效应的介质效应。在系统的势和弹性横截面上可以清楚地看到介质的影响。介质效应的关键作用也通过其他有效的核子-核子（）相互作用得到证实。此外，本文的方法也适用于其它重离子弹性散射系统。同样，介质效应在重离子弹性截面中清晰可见。随着靶质量和入射能量的增加，介质对弹性截面的影响变得不明显。然而，介质效应对于修复重离子散射也很重要。最后，我们明确了TBF效应在核-核弹性散射中的关键作用。
We investigate the property of the high-density nuclear matter probed by the nucleus-nucleus elastic scattering in the framework of the double-folding model with the complex-matrix interaction. The medium effect including the three-body-force (TBF) effect is investigated with present two methods based on the frozen density approximation. The medium effect is clearly seen on the potential and the elastic cross section for thesystem at. The crucial role of the medium effect is also confirmed with other effective nucleon-nucleon () interactions. In addition, the present methods are applied to other heavy-ion elastic scattering systems. Again, the medium effect is clearly seen in the heavy-ion elastic cross section. The medium effect on the elastic cross section becomes invisible with the increase of the target mass and the incident energy (up to). However, the medium effect is again important to fix the heavy-ion scattering over. Finally, we make clear the crucial role of the TBF effect up toin the nucleus-nucleus elastic scattering.
