Abstract
The absorption of 239 MeV positive pions on He-3, He-4, N, and Ar is s tudied. A strong enhancement is seen in the differential cross section s in the kinematic region associated with free pi-p scattering. This e nhancement is interpreted as a clear signature of initial state intera ctions in the absorption of pions on nuclei.
