摘要：

A theoretical description of nucleon knockout reactions initiated by polarized electron scattering from polarized nuclei is presented. Explicit expressions for the complete set of reduced response functions (independent of the polarization angle) that can be experimentally obtained assuming plane waves for the electron are given in a general multipole expansion. The formalism is applied to the particular case of closed-shell-minus-one nuclei using two models for the ejected nucleon. including the final-state interaction phenomenologically with a complex optical potential and in the Factorized plane-wave impulse approximation. Relativistic effects in the kinematics and in the electromagnetic current are incorporated throughout-specifically a new expansion of the electromagnetic current in powers only of the struck nucleon momentum is employed. Results are presented For the nucleus K-39. (C) 1998 Academic Press.
