Total and partial photoproduction cross sections at 1.44, 2.8, and 4.7 GeV

A nearly monochromatic high-energy photon beam produced by Compton backscattering of ruby laser light has been used to study photoproduction in a hydrogen bubble chamber. The total hadronic γp cross sections at 1.44, 2.8, and 4.7 GeV are found to be 145.1 ± 5.7, 131.3 ± 4.3, and 124.2 ± 3.9 μb, respectively. Partial cross sections are presented also. © 1969 The American Physical Society.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
