The statistics for 3χ104 primary stars, which were identified as a result of irradiation of emulsion nuclei by 70-GeV protons and 50-GeV π " mesons, were used to record particles with a lifetime of 10~14-10~13 sec. Two events were associated with semileptonic decays and three events were identified as hadronic decays of neutral particles.
