We have successfully performed a demonstrative electron scattering experiment using the SCRIT technique, which is exclusively developed for electron scattering experiments off rare-produced, short-lived nuclei. (Phys. Rev. Lett. 102, 102501 (2009))

A luminosity of an order of 1026 /cm2/s, high enough for elastic electron scattering, was obtained using only 106 trapped ions at the averaged electron beam current of 75 mA. The angular distribution of elastic scattering from the trapped Cs ions was successfully measured. This success clearly proves that electron scattering off short-lived nuclei is now practical with the SCRIT technology.

In the seminar, I will describe the results of this experiment in details with an introduction to electron scattering. In addition, future perspectives at an electron scattering facility for short- lived nuclei at RIBF, which is under construction, will be given.
