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