Absolute photon flux measurement at the BGO-OD experiment and Cross-Check with π⁰ p production* — •Katrin Kohl for the BGO-OD collaboration — Physikalisches Institut, Universität Bonn

The BGO-OD experiment at the ELSA accelerator facility at Bonn investigates the internal reaction mechanisms of meson photoproduction off the nucleon. Absolute normalisation of the flux of tagged photons is indispensable for cross section determination. In this talk the measurement principle is presented and the obtained flux is checked with the known cross section of the reaction γ p→ π⁰ p.
