Spin entanglement produced from elastic scattering of unpolarized electrons — •Rustam Berezov, Sebastian Böttger, and Joachim Jacoby — Inst. f. Ang. Phys., Max von Laue-Str. 1, JWG-Univ. Frankfurt/Main

A Moeller scattering experiment is set up where a beam of unpolarized electrons is scattered quasi elastically from a target. In this case entanglement appears if the two particles are indistinguishable. For identical fermions the scattering cross-section to 90 in the center of mass system is forbidden, whereas for identical bosons the scattering cross-section at that angle is twice as big as the one for distinguishable particles. Therefore scattering of electrons to 90 is only permitted for distinguishable electrons, where the spin orientation for both scattered electrons is anti-correlated. A new design of a spin detector is proposed to detect the spin of the electrons.
