The mass spectra of the ωπ0 system, produced in π-p charge-exchange reactions at 38 GeV/c and 100 GeV/c, show a new neutral state with a mass of 2200±20 MeV and a width of 260±50 MeV. Like ρ3(1690), this meson, X(2200), is produced through one-pion-exchange. X(2200)JPC is likely 1--. It might be a 23D1 radial-orbital excitation of ρ0. Its production cross section falls with energy quadratically, in agreement with one-pion-exchange. The cross sections for b1(1235) and ρ3(1690) production have also been measured; their energy dependences have been determined. © 1992 Springer-Verlag.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
