We examine meson dynamics in in-medium antinucleon-nucleon annihilation in
the framework of modified Skyrme model which takes into account nuclear mat
ter effects, The number of the in-radiation zone produced pions is calculat
ed. We find that multiplicity of produced pions is suppressed with increasi
ng of the medium density. (C) 2000 Elsevier Science B.V. All rights reserve
