Description
The linearly polarized photon beam at the High Intensity gamma-ray Source (HIgS) was used to study neutron emission from a {nat}Hg target at energies of 11, 12, 13, 14, and 15 MeV. Twelve liquid scintillator detectors were placed at polar angles of 55 degrees, 90 degrees and 125 degrees and at azimuthal angles of phi=0 degrees, 90 degrees, 180 degrees, 270 degrees. Six more detectors were placed at polar angles of 72 degrees, 107 degrees, and 142 degrees at phi=0 degrees and 90 degrees. The ratio of neutron yields parallel to neutron yields perpendicular to the plane of polarization were determined as a function of E_gamma, E_n, and theta. Results will be discussed.
