Outline of Final Research Achievements

We aim at studying the internal structures of production-hard short-lived unstable nuclei by means of electron scattering. Electron scattering is the best probe for such studies and indeed it has played consistently an essential role to reveal the detailed internal structures of many stable nuclei. An innovative technology, named SCRIT, we have invented has been demonstrated to be a way to realize never-yet-performed electron scattering off short-lived nuclei. We have completed the construction of the world’s first electron scattering facility dedicated for short-lived nuclei, and started its operation. Recently, the first physics data was obtained.
