Abstract

First results on meson spectroscopy using antineutrons as projectiles are reported. Three-body (π⁺π⁺π^-) and five-body (π⁺π⁺π⁺π^-π^-) final states following the annihilation of 100 to 290 MeV/c antineutrons on hydrogen were analyzed. The (π⁺π^-) invariant mass spectrum in the three-body reaction is accounted for by the ρ{variant}⁰ anf f₂(1270) resonances, together with an enhancement around 1540 MeV, in the region of the AX (1565) and the f₂(1515) resonances, whereas the best fit for the (π⁺π⁺π^-π^-) invariant mass in five-body events shows the already reported structure ζ(1480) and suggests the presence of a second structure around 1650 MeV.
