Radiative decays of [eta, rho, omega, eta'] mesons produced in the reaction [pi-]+p [yields] meson + n at 8.45 Gevc

We have studied the radiation decays of non strange mesons into (pi)('+),(pi)('-) and one or three gamma rays observed in the reaction / (pi)('-) + p (--->) Meson + n / at beam momentum 8.45 Gev/c in a Counter-Spark chamber experiment conducted at Argonne National Laboratory Zero Gradient Synchrotron. / We set a new apper limit on the branching ratio (omega) (--->) (pi)('+)(pi)('-)(gamma) which is almost an order of magnitude smaller than the previously set upper limit. / We present a high statistics independent measurement of the branching ration (eta)' (--->) (rho)(gamma). / We observed the decays (rho) ((omega)) (--->) (eta)(gamma) for the first time in the reaction / (pi)('-)p (--->) (rho) ((omega))n / and measured the decay rates (GAMMA)(,(rho)((omega)) (--->) (eta)(gamma)).
