Abstract

Two sharp structures at about 1200 MeV/c2 and 1400 MeV/c2 are observed in the pi+-pi--pi+-pi--system invariant mass in antiproton-He-4 annihilation at rest. No similar signals are seen in the corresponding antiproton-proton data. A similar observation has been made in the streamer chamber data (see Ref. 1).
