Abstract

The laser Compton scattering gamma ray beamline at the synchrotron light facility NewSUBARU supplies a quasi-monochromatic, polarized, high-energy photon beam. A gamma ray flux of more than 107 photons/s is generated at a photon energy range of 1 - 73 MeV. Emission distributions of the fast neutrons generated from different target materials were measured as a function of the polarization angle of the linear polarized gamma-ray beam using a time-of-flight method with fast plastic scintillators. The neutron distributions were consistent with a previous theoretical result. The relatively slow neutrons were measured via an activation method. The result demonstrated the small anisotropy of the slow neutron emission.
