摘要：

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