The influence of the residual ph tensor force on the wave function of the 5.846 MeV isoscalar 1/sup +/ state in /sup 208/Pb is investigated. While the (e,e') form factor is well described within a 1p1h random-phase-approximation model and is fairly insensitive to the strength of the tensor force, medium energy proton scattering experimental angular distributions are not reproduced within this model. It is demonstrated that the inclusion of 2p2h excitations yields screening corrections to the effective tensor force which reduce its strength considerably. Thus the apparent failure of the 1p1h random-phase-approximation wave function to describe the inelastic proton scattering data at medium energy can be resolved.
