摘要：

We report on microscopic calculations for the He-4 compound system in the framework of the resonating group model employing realistic nucleon-nucleon and three-nucleon forces. The resulting scattering phase shifts are compared with those of a comprehensive R-matrix analysis of all data in this system, which are available in numerical form. The agreement between calculation and analysis is very good in most cases. Adding three-nucleon forces yields large effects in many cases. For a few cases, the new agreement is striking. We relate some differences between calculation and analysis to specific data and discuss experiments necessary to clarify the situation. From the results, we conclude that the data of the He-4 system might be well suited to determining the structure of the three-nucleon force.
