Title: Electron Scattering Off Online-produced Radioactive Isotope - first results from RIKEN SCRIT e-scattering facility

Speaker: Toshimi Suda (Tohoku University, Sendai, Japan)

Abstract: In this seminar, I will present the results of the world's first electron scattering off an online produced radioactive isotope. This achievement was recently accomplished at the RIKEN SCRIT electron-scattering facility in Japan.

The SCRIT facility is designed to probe the internal structures of short-lived exotic nuclei by electron scattering. This facility employs a novel ion-trapping technique, named SCRIT (Self-Confining Radioactive Isotope Ion Target), to prepare a target of exotic nuclei for electron scattering on an energetic electron beam (Ee = 150 - 300 MeV).

By utilizing only ~107 ions of an exotic nucleus, the SCRIT target technique allows us to achieve a luminosity of approximately 1027 /cm2/s, which is the minimum required for realizing elastic electron scattering.

I will discuss the experimental results in detail and the SCRIT facility as well. In addition to elastic scattering, I would like to mention possible additional research possibilities at the SCRIT facility.

If time permits, I would also like to introduce our low-energy electron scattering project, ULQ2 (Ultra-Low Q2), which aims to determine the proton charge radius through extremely low-energy electron scattering with Ee = 10 - 50 MeV.
