At the GRAAL facility, a polarised and tagged ray beam is produced in the energy range from 500 MeV up to 1500 MeV. Results of beam polarisation asymmetries and cross sections for the photoproduction of η and π0 on the proton are presented. These very precise measurements cover the angular range 30°-150°, providing stringent constraints to theoretical models.

Abstract
At the GRAAL facility, a polarised and tagged ray beam is produced in the energy range from 500 MeV up to 1500 MeV. Results of beam polarisation asymmetries and cross sections for the photoproduction of η and π0 on the proton are presented. These very precise measurements cover the angular range 30°-150°, providing stringent constraints to theoretical models.File in questo prodotto:
