Times Cited Count:18 Percentile:74.49(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.

Times Cited Count:75 Percentile:97.91(Instruments & Instrumentation)A new laser Compton ray source in the energy range of several-MeV was developed using a CO laser at the NewSUBARU electron storage ring. When the electron energies were 974, 1220 and 1460 MeV, the maximum ray energies were measured to be 1.72, 2.72, and 3.91 MeV. The luminosity of the rays was 7300 photon/mA/W/s and a flux of 5.810 photon/s was achieved. These performances agreed with calculations. This generation of rays is in a no-loss mode for the storage electrons, and the maximum flux was limited only by the power of the laser.

Times Cited Count:29 Percentile:82.75(Physics, Nuclear)We report a half-life of the ground state of Re populated by the ReRe reaction with the laser Compton scattering -rays generated through relativistic engineering. The -rays are provided at the electron storage ring NewSUBARU. The previous experiment using deuteron-induced reactions has yielded a recommended half-life of the 3 ground state of Re to be 38.0 0.5 d, including a possible contribution from the 8 isomer ( = 169 8 d) of Re since the presence of the isomer was not known at that time. In contrast, the reaction has an advantage to selectively populate the ground state because this reaction does not bring large angular momentum. The measured half-life of 35.4 0.7 d is shorter than the previous half-life by about 7%. This difference is crucial for applications using the activation method.

Times Cited Count:142 Percentile:96.4(Chemistry, Physical)The main components of a new beamline for surface and interface crystal structure determination at SPring-8 are briefly described. Stages for the beamline monochromator are modified for making an incident X-ray intensity more stable for surface X-ray experiments. Absolute photon flux densities were measured with an incident photon energy. A new ultrahigh vacuum system is introduced with preliminary X-ray measurements from an ordered oxygen on Pt(111) surface.

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.
