“…H. Rosenfeld and P. Sliding, Photoproduction of Vector Mesons-Experimental, Lawrence Berkeley Laboratory Report LBL-539, submitted to Proceedings of the Inter national School of Subnuclear Physics, Erice, Sicily, July 1971. 5 The laser beam has been made to work down to 760 MeV, and the following pictures have been taken to study photoproduction with polarized photons in the "2nd" and "3rd" resonance regions. In The CERN 81-cm bubble chamber was exposed to antiprotons with momenta between 1.0 and 1.6…”
