Three-body-force effect on nucleus-nucleus elastic scattering

The three-body force (TBF) effect is studied in nucleus-nucleus elastic scattering with the use of a new complex G-matrix interaction that reproduces well proton-nucleus scattering observables. The TBF contribution is included in the G-matrix so as to give a reasonable nuclear-matter saturation curve. The O-16 + O-16 potential is obtained by the double-folding procedure with the G-matrix interaction. The observed cross sections for O-16 + O-16 elastic scattering at E/A = 70 MeV are nicely reproduced up to the most backward scattering angles when the TBF effect is included.
