利用一种新的复数G矩阵相互作用，研究了核-核弹性散射中的三体力(TBF)效应。为了给出合理的核物质饱和曲线，在G矩阵中包含了TBF的贡献。通过G-矩阵相互作用的双折叠过程得到了{sup 16}O+{sup 16}O势。当计入TBF效应时，观测到的E/A=70 MeV的{sup 16}O+{sup 16}O弹性散射截面在最大后向散射角范围内都能很好地再现。
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 {sup 16}O+{sup 16}O potential is obtained by the double-folding procedure with the G-matrix interaction. The observed cross sections for {sup 16}O+{sup 16}O elastic scattering at E/A=70 MeV are nicely reproduced up to the most backward scattering angles when the TBF effect is included.
