We study the role of the nuclear medium on the pion spectra after the antiproton annihilation at rest in nuclei. The nuclear medium acts as a scatterer and an absorber of outgoing pions and modifies the pion energy spectra. The pion spectra seem to be reproduced by assuming. that half of the pions moving outward go out freely, while the other half moving . inward to the nucleus are absorbed by nucleons according to the Jr-nilcleus absorption cross sections. We propose a coincidence experiment to verify this picture.
