Abstract
A method has been developed to measure differential crosssections for photoproduction of neutral pions from hydrogen below 260 MeV incident photon energies. Tye recoil protons are detected in coincidence with one of the decay γ-rays of the pion. The proton counter telescope utilizes a proportional gas counter as transmission counter. A lead glass cerenkov counter detects the γ-rays. A thin liquid hydrogen target with Mylar walls is used. Some cross-sections measured at 90‡ in the center of mass are presented.
