Abstract
The first measurements of the induced proton polarization, Pn, for the 12C (e,e'p) reaction are reported. The experiment was performed at quasifree kinematics for energy and momentum transfer (ω,q) ≈ (294 MeV, 756 MeV/c) and sampled a recoil momentum range of 0-250 MeV/c. The induced polarization arises from final-state interactions and for these kinematics is dominated by the real part of the spin-orbit optical potential. The distorted-wave impulse approximation provides good agreement with data for the 1p3/2 shell. The data for the continuum suggest that both the 1s1/2 shell and underlying l > 1 configurations contribute.
