The double pi(0) and omega-meson photoproduction at GRAAL (original) (raw)

Nstar 2002: Proceedings of the Workshop on the Physics of Excited Nucleons, 2003

Abstract

The double pi0 and omega-meson photoproduction have been measured at GRAAL. The total and differential cross sections and the beam asymmetry were deduced. In the double pi0 channel, the total cross section is dominated by two peaks at 0.7 and 1.1 GeV of beam energy, the second one having been seen for the first time. The interpretation of the double
