MESON-EXCHANGE CURRENT EFFECTS IN ELASTIC ELECTRON-SCATTERING FROM POLARIZED NUCLEI

The effects of the meson-exchange currents in the elastic scattering of polarized electrons by polarized nuclei are investigated. In particular some stable doubly closed-shell +/- 1 nucleon nuclei are considered in the framework of the extreme shell model. We set the conditions of observability of such effects and present the situations where such conditions are fulfilled for the studied nuclei: B-11, C-13, 15, O-17 and K-39. Different target polarizations have been considered. We find that the most advantageous cases correspond to an on-plane polarized target and a polarized electron beam, simultaneously.
