Times Cited Count：17 Percentile：74.37(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.

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 + bcos() 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.

The M1 strength in atomic nuclei is important for estimation of neutrino-nucleus interactions in supernovae. We have proposed a method using (, n) reactions with linear polarized laser Compton scattering (LCS) -rays to measure the M1 strength and verified a theoretical prediction for the first time.
