摘要：

The central production of rho-0, f2 and rho-3(0) mesons is observed for the first time in processes which are originated by pi+ p reactions proceeding via baryon exchange mechanism. The data come from the CERN WA56 experiment designed to separate the baryon exchange reactions in pi+ p-collisions at 20 GeV/c. We report on the measured integral and differential cross sections and also give the density matrix elements of the meson resonances observed.
