The first elastic electron scattering has been successfully performed at the self-confining radioactive-isotope ion target (SCRIT) facility, the world’s first electron scattering facility for SCRIT technique achieved high luminosity (over ${10}^{27}{\mathrm{cm}}^{-2}{\mathrm{s}}^{-1}$, sufficient for determining the nuclear shape) with only ${10}^8$ target ions. While ${}^{132}\mathrm{Xe}$ used in this time as a target is a stable isotope, the charge density distribution was first extracted from the momentum transfer distributions of the scattered electrons by comparing the results with those calculated by a phase shift calculation.
