Graal: a polarized gamma ray beam at ESRF
The GRAAL facility produces a highly polarized gamma-ray beam by Compton scattering of laser photons on the electrons of the European Synchrotron…
Break-up and Coherent Photoproduction of η Mesons on the Deuteron
We present new break-up and coherent data for η meson photoproduction on the deuteron, using a deuterium target and tagged bremsstrahlung photons up…
Role of the Roper resonance in the eta-meson photoproduction
All sixteen observables for the reaction gamma + p --> eta + p have been investigated from threshold up to 1.2 GeV. The formalism is based on an…
