Spin-polarization response functions in high-energy ({rvec e},e{sup {prime}},{rvec p}) reactions
Spin-polarization response functions for the high-energy ({rvec e},e{sup {prime}}{rvec p}) reaction are examined by computing all 18 response functions for proton kinetic energies of 0.515 and 3.170 GeV from an {sup 16}O target. The Dirac eikonal formalism is applied to account for the final-state interactions. It is found to yield the response functions in good agreement with those calculated by partial-wave expansion at 0.5 GeV. We identify the response functions that are dominantly determined by the spin-orbit potential in the final-state interaction. Dependence on the Dirac- or Pauli-type current of the nucleon is investigated in the helicity-dependent response functions, and the normal-component polarization of the knocked-out proton is computed. {copyright} {ital 1997} {ital The American Physical Society}
