(Team Leader: Masanori Wakasugi)
We aim at the investigation of internal nuclear structure of short-lived radioactive nuclei (RI) by means of electron scattering. Electron scattering for RI's has never been performed duo to inability to make target of these nuclei. We have developed a novel internal target system named SCRIT (Self-Confining RI Ion Target) in an electron storage ring to make the experiment with a compact experimental system. Construction of the SCRIT electron scattering facility was started in 2009, and operation of electron accelerators, RTM and SR2, was started in 2010. Test experiments of the SCRIT system equipped in SR2 were performed in 2011-2012 to evaluate the SCRIT performances. The luminosity was reached to 10^27/(cm^2s) in case of 10^8 ions injection into the SCRIT, and the confinement lifetime was over 1s. These are performances satisfactory to the electron scattering experiment. On the other hand, an ISOL type of RI generator (ERIS) has been developing. ERIS was constructed in 2011 and commissioned in 2012. In 2015, the construction of the detector system for scattered electrons are completed and it has been commissioned. In 2016, we succeeded in measurements of the momentum transfer distribution of the elastically scattered electrons from132Xe isotopes and in determination of the nuclear charge density distribution. We are now preparing the first experiment for unstable nuclei.
