Spin-orbit distortion of the emerging nucleon in quasi-free electron scattering

Spin-orbit distortion of the emerging nucleon in quasi-free electron scattering is considered in the frame of a program aiming at examining the approximations involved in the theoretical treatment. The imaginary part of the spin-orbit coupling in the optical-model potential felt by the knocked out nucleon appears here to have a significant role. Its consequences in the case of the reaction ¹²C(e, e′p)¹¹B are discussed.
