Pion photoproduction from the deuteron in the Delta Region

and the LEGS-SPIN Collaboration

A series of pion photoproduction measurements have been carried out at the LEGS facility using linearly polarized photons in the delta resonance region and a series of unpolarized targets which included liquid hydrogen, liquid deuterium, and solid hydrogen-deuteride. The Spin-ASYmmetry (SASY) detector array provided large solid-angle coverage and the ability to simultaneously collect and separate signals from the individual photoproduction channels. Both charged and neutral pion channels have been extracted from both protons and neutrons. Preliminary Results will be presented, and the problem of inferring free neutron quantities from bound neutron observables will be discussed.
