Spatial anisotropy of neutrons emitted from the $$^{56}$$Fe($$gamma$$, n)$$^{55}$$Fe reaction with a linearly polarized $$gamma$$-ray beam

We have measured the azimuthal anisotropy of neutrons emitted from the $$^{56}$$Fe($$gamma$$, n)$$^{55}$$Fe reaction with a linearly polarized $$gamma$$ ray beam generated by laser Compton scattering at NewSUBARU. Neutron yields at the polar angle of 90$$^{circ}$$ have been measured as a function of the azimuthal angle $$phi$$ 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 $$a$$ + $$b$$cos(2$$phi$$).

Size-selective extended X-ray absorption fine structure spectroscopy of free selenium clusters

Physical Review Letters, 89(24), p.243401_1 - 243401_4, 2002/12

 Times Cited Count：16 Percentile：65.1(Physics, Multidisciplinary)

Recently, we proposed a new method for the size-selective EXAFS(Extended X-ray absorption fine structure) of neutral-free culsters, in which not only the X-ray absorption process but also the deexitation process are utilized as the structural information. In order to verify this method experimentally, we have developed the synchronous measurements of EXAFS and photoelectron photoion coincidence and carried them out for a Se cluster beam by utilizing the third-generation intense X-ray source. The EXAFS spectra for Se small clusters have been obtained and compared critically with theoretical predictions.
