Descripción
Compton backscattering gamma ray beams are characterized by a high
degree of linear and circular polarization with low unpolarized
backgrounds and have proven to provide very precise measurements of
polarization observables. Latest results from LEGS and GRAAL experiments
on proton and deuteron targets are presented. The Σ beam asymmetry
for ω photoproduction has been measured by the GRAAL collaboration
for both the ω→π0γ and the
ω→π+π-π0 decay
channels on the proton target; single and double polarization
asymmetries have been provided also for the K photoproduction channel. E
and G double polarization asymmetries for single pion photoproduction on
the proton and deuteron have been measured at LEGS using a frozen spin
HD target.
