Abstract
The imaginary central and spin-orbit components of the .1.-nucleus optical potential are investigated in a 11'-exchange model. It is found that the effective spin-orbit interaction of the isobar reflects lárge nonlocalities from true pion absorption and from the quasielastic á. decay. The parameters for the absorption and the spin-orbit strength are in qualitative agreement with recent phimomenological results.
