Abstract The absorption of 239 MeV positive pions on {sup 3}He, {sup 4}He, N, and Ar is studied. A strong enhancement is seen in the differential cross sections in the kinematic region associated with free {pi}-{ital p} scattering. This enhancement is interpreted as a clear signature of initial state interactions in the absorption of pions on nuclei. {copyright} {ital 1996 The American Physical Society.}
