Antiproton annihilation at the center of 40Ca and 108Ag nuclei is studied in the frame of an intranuclear cascade model. Primordial pions, issued from the annihilation, produce a density wave, which ejects about one fifth of the nucleons. The spectra of the emerging nucleons and of the produced pions are studied. For the latter, the spectrum deviates from a thermal law.
