A polarised and tagged (gamma) ray beam is produced at GRAAL by the Compton scattering of laser light on the high energy electron of the ESRF storage ring. We present results on the beam polarisation asymmetries and cross sections in the photoproduction of mesons on hydrogen and deuterium target in the energy region 500-1500 MeV. These very precise results cover the angular range 30 degrees-150 degrees, providing stringent constraints to theoretical models.

Abstract
A polarised and tagged (gamma) ray beam is produced at GRAAL by the Compton scattering of laser light on the high energy electron of the ESRF storage ring. We present results on the beam polarisation asymmetries and cross sections in the photoproduction of mesons on hydrogen and deuterium target in the energy region 500-1500 MeV. These very precise results cover the angular range 30 degrees-150 degrees, providing stringent constraints to theoretical models.| File | Dimensione | Formato | |
