Angular distribution of the target asymmetry on polarized protons for the reaction γp↑ → π +n at a photon energy of 700 MeV

At the Bonn 2.5 GeV electron synchrotron the angular distribution of the target asymmetry T = (σ↑ − σ↓) (σ↑ + σ↓) for the reaction γp↑ → π +n was measured at a mean photon energy of 700 MeV and pion CM-angles from 50° to 155°. The combination of a 3He-cryostat, polarizing the free protons in the tar...

Description
Summary:At the Bonn 2.5 GeV electron synchrotron the angular distribution of the target asymmetry T = (σ↑ − σ↓) (σ↑ + σ↓) for the reaction γp↑ → π +n was measured at a mean photon energy of 700 MeV and pion CM-angles from 50° to 155°. The combination of a 3He-cryostat, polarizing the free protons in the target up to 65%, with a large acceptance magnet for pion detection led to statistical errors of the target asymmetry comparable with those of cross section measurements.
