Photoproduction of vector mesons (II)

Cross sections for the production of ω- and ρ{variant}-mesons in photon-nucleon collisions have been extended to include additional angles and higher energies. While in the case of ω, the OPE model is prodeminant, it is found that the for ρ{variant}-production, the nucleon, the intermediate state is strinkingly significant. © 1967.
