摘要：

Cross sections for 0 photoproduction from hydrogen in the backward direction have been measured for photon energies of 6, 8, 12, and 18 GeV. The range of momentum transfer covered in these measurements is -1 (GeVc)2<u<0(GeVc)2, ddu is found to have a backward peak and decreases with energy as s-3.00.2. Photoproduction of 0 and 0 mesons has also been observed. © 1969 The American Physical Society.
