Abstract
Backward angle measurements with the A4 setup at Mainz have been performed and are ongoing. Differently as with the forward measurements severe background issues had to be faced, due to γ-events generated by the π 0 decay. Hardware upgrades as well as data analysis improvements were needed. For the latest a detailed study of the background by means of Monte Carlo simulations has been undertaken. Its major features together with the basic ansaetze of the γ-background handling are presented in this contribution.
