摘要：

The charge-exchange reaction pi p -> w(780)phi(1020)n is studied with the VES setup. The (w phi) system is observed at relatively low background. Its invariant mass distribution peaks near threshold. The two-particles partial wave analyses shows that the J(PC) = 0(++) state dominates. Comparison with scalar wave in ww system at the comparable mass gives evidence for violation of the OZI rule. Another subject is a search for possible transition f(0)(980) -> a(0)(980), which violates the isospin symmetry.
