Spatial anisotropy of neutrons emitted from the <mml:mprescripts></mml:mprescripts>56Fe(γ ,n )<mml:mprescripts></mml:mprescripts>55Fe reaction with a linearly polarized γ -ray beam
Abstract
We have measured the azimuthal anisotropy of neutrons emitted from the <mml:mprescripts></mml:mprescripts>56Fe(γ ,n )<mml:mprescripts></mml:mprescripts>55Fe reaction with a linearly polarized γ -ray beam generated by laser Compton scattering at NewSUBARU. Neutron yields at the polar angle of 90∘ have been measured as a function of the azimuthal angle ϕ between the detector and the linear polarization plane of the γ -ray beam. The azimuthal anisotropy of neutrons measured at ϕ =0∘ , 10∘, 25∘, 45∘, 60∘, 70∘, and 90∘ has been well reproduced using a theoretically predicted function of a +b cos(2 ϕ ) .
