Measurements Of Spin Observables In Single Pion Photo-Production From Polarized Quasi-Free Neutrons In Solid Hd

Psuedo-scalar meson photo production measurements have been carried out with longitudinally-polarized neutrons using the circularly and linearly polarized photon beams and the CLAS at Thomas Jefferson National Accelerator Facility (Jlab). The experiment aims to obtain a complete set of spin observables on an effective neutron target using D in HD. Preliminary E and Sigma asymmetries for the exclusive reaction, gamma + n(p) -> pi(-) + p(p), are discussed.
