The Sekiguchi Three-Body Nuclear Forces Project (TOMOE Project) aims to understand the fundamental mechanisms of the manifestation of nuclear properties (nuclear properties) and to apply them to applied science. For a long time, the nuclear forces that create nuclear properties were explained only by the two-body nuclear forces acting between two nucleons, but recent studies have made clear that three-body nuclear force is needed when three nucleons act simultaneously. This project will conduct high-precision experiments, establish a theory, and determine the three-body nuclear forces. Then development a quantum many-body precision calculation method using the obtained nuclear forces will describe nuclear properties. This report introduces overview and challenges of this project reaching to the production of nuclear data.
