Abstract
Some cross-sections for the photo-production ofπ 0-mesons from hydrogen for pion c.m. angles in the range 60°–125° are presented. The data have been obtained by measuring proton yields from a hydrogen target, thus permitting separation of single-pion production from the strong background caused by double-pion production. The values, which extend from 360 to 938 MeV, show reasonable agreement with the results of a recent phase-shift analysis.

We wish to thank the synchrotron running-crew under R. Alvinsson, the mechanical workshop under P. Jensen and L. Thånell and the electronic workshop under G. Held for their continuous support throughout these measurements. A large part of the apparatus used was purchased through a grant from Riksbankens Centenary Fund. The IBM 1800 computer was a gift from the Wallenberg Foundation. We wish to express our thanks to both these bodies and to Professors B. Forkman and G. von Dardel for their interest and encouragement. Last but not least, Mrs. I. Hammar showed her usual patience in typing and re-typing the various states of the manuscript.
