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

Abstract

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 $^{16}\mathrm{O}$$+$$^{16}\mathrm{O}$ potential is obtained by the double-folding procedure with the $G$-matrix interaction. The observed cross sections for $^{16}\mathrm{O}$$+$$^{16}\mathrm{O}$ elastic scattering at $E/A=70$ MeV are nicely reproduced up to the most backward scattering angles when the TBF effect is included.
