AbstractAbstract
[en] We have investigated ω production in the reaction π-p → ωn very close to threshold. The dependence of the mass, width, branching ratio, and cross section upon the final-state c.m. momentum, P*, were studied. The mass and width were independent of P* with values of 782.4 +- 0.5 and 10.22 +- 0.43 MeV, respectively. The branching ratio GAMMA(ω → π0γ)/GAMMA(ω → π+π-π0) was also constant, having a value of 0.084 +- 0.013. An upper limit of 0.18 was set on the branching ratio GAMMA(ω → π0π0γ)/GAMMA(ω → π0γ). We observed a rapid fall in the cross section below P* = 100 MeV/c. This could not be explained in terms of S-wave production alone, but could be fitted by a resonant P wave plus a noninterfering S wave
