Abstract

We propose a new colliding system of electrons and radioactive (unstable nucleus) ions, in which a high-energy electron beam collides with its self-confining radioactive ions in a target region locally formed in an electron storage ring. These ions are transversely confined in the electron stream by repetitious transverse focusing kicks given by electron bunches, and are drifting back and forth between electrostatic mirrors. In the present paper, a practical application of this system is described to a specific electron-scattering experiment on a double-magic unstable 132Sn nucleus to measure its unknown charge distribution. We discuss performance of the target and estimate the achievable luminosity.
