Medium effect in high-density region probed by nucleus-nucleus elastic scattering

Understand

We investigate the sensitivity of the medium effect in the high-density region on the nucleus-nucleus elastic scattering in the framework of the double-folding (DF) model with the complex $G$-matrix interaction.

• The medium effect including three-body-force (TBF) effect is investigated with two methods.
• In the both methods, the medium effect is clearly seen on the potential and the elastic cross section.
• Finally, we make clear the crucial role of the TBF effect up to $k_F =$ 1.6 fm$^{-1}$ in the nucleus-nucleus elastic scattering.
