STUDY OF THE A-PHI ASYMMETRY ON THE LIGHTEST NUCLEI

The consequences of Lorentz covariance and of conservation of the nucl ear current in calculations of the A(phi) asymmetry of the cross secti ons of (e,e'p) reactions on few-nucleon systems are studied. It is sho wn that the magnitude of A(phi) is very sensitive to various relativis tic effects and to the conservation of the nuclear current. In the qua si-elastic region (q2/2mnu is similar to 1,p(mis)/m much less than 1), this asymmetry is determined solely by the degree of linear polarizat ion of the virtual photon and by the structure of the electromagnetic current, and at proton emission angles theta(p)c.m. > 50-degrees the A (phi) asymmetry is determined both by the reaction mechanisms and by t he intranuclear dynamics.
