ω-Production on a Neutron Target at ANKE — •I. Lehmann1 and S. Barsov2 — 1Forschungszentrum Jülich — 2PNPI, Gatchina
In August 2001 a test beam time to investigate the reaction: pd→ psp d ω took place at ANKE/COSY. It could be shown, that the slow spectator proton (Tkin = 2.5 − 30 MeV) can be identified simultaneously with the fast deuteron (p ≈ 2 GeV/c) in the detection systems of ANKE. The former is detected in a near-target-silicon telescope and the latter is identified using the momentum resolution of the magnetic spectrometer together with energy losses in two layers of scintillators and the response from inclined Čerenkov counters.
In the talk the methods to determine the ω-cross section from a missing mass spectrum with large background from multi-pion and ρ-production will be discussed and preliminary results will be presented.
