Times Cited Count：7 Percentile：49.18(Physics, Nuclear)We have measured the azimuthal anisotropy of neutrons emitted from the Fe(, n)Fe reaction with a linearly polarized 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 
between the detector and the linear polarization plane of the ray beam. The azimuthal anisotropy of neutrons measured at seven angles has been well reproduced using a theoretically predicted function of 
+ 
cos(2).

Times Cited Count：18 Percentile：73.11(Astronomy & Astrophysics)It was predicted in 1950's, the neutron angular distribution in (, n) reactions with a 100% linearly polarized -ray beam should be anisotropic and described by a simple function of a + b sin
at 90 on the beam axis but it has not been experimentally confirmed for middle-heavy nuclides over than half a century. We have verified experimentally this angular distribution on 
Au, 
I, and natural Cu using linearly polarized laser Compton scattering -rays at NewSUBARU.

Japan Atomic Energy Agency (JAEA) at Tono Geoscience Center (TGC) is pursuing a geoscientific research and development project namely the Mizunami Underground Research Laboratory (MIU) Project in crystalline rock environment in order to construct scientific and technological basis for geological disposal of High-level Radioactive Waste (HLW). The MIU Project has three overlapping phases: Surface-based Investigation phase (Phase I), Construction phase (Phase II), and Operation phase (Phase III). The MIU Project has been ongoing the Phase II. And Phase III started in 2010 fiscal year. This report shows the results of the investigation, construction and collaboration studies in fiscal year 2010, as a part of the Phase II based on the MIU Master Plan updated in 2002.

It was predicted in 1950's that the neutron angular distribution in (,n) reactions with a 100% linearly polarized -ray beam for dipole excitation should be anisotropic and universally described by the simple function of a + b
cos(
) at polar angle 
= 90, where is the azimuthal angle,but it has not been experimentally confirmed over half a century. We have verified experimentally this angular distribution on three targets using linearly polarized laser Compton scattering -rays at NewSUBARU.

In 1950's, Agodi predicted that the neutron angular distribution in (, n) reactions with a 100% linearly polarized -ray beam for dipole excitation should be anisotropic and universally described by the simple function of a + bcos()at polar angle =90, where is the azimuthal angle, but it has not been experimentally confirmed over half a century. The work by Agodi had been forgotten after 1970's. We have verified experimentally this angular distribution on three targets using linearly polarized laser Compton scattering -rays at NewSUBARU for the first time.
