Times Cited Count：39 Percentile：86.89(Physics, Nuclear)Using quasi-monochromatic laser-Compton scattering rays, total photoneutron cross sections were measured for 
Pb near neutron threshold with a high-efficiency 4
neutron detector. Partial 
1 and 
1 photoneutron cross sections along with total cross sections were determined for Pb at four energies near threshold by measuring anisotropies in photoneutron emission with linearly-polarized rays. The 1 strength dominates over the 1 strength in the neutron channel where 1 photoneutron cross sections show extra strength of the pygmy dipole resonance in Pb near the neutron threshold corresponding to 0.32-0.42% of the Thomas-Reiche-Kuhn sum rule. Several 
units of B(1)
strength were observed in Pb just above neutron threshold, which correspond to an 1 cross section less than 10% of the total photoneutron cross section.

5" NaI(Tl) detector for blank and three lead materials of 75.8, 50.9, and 25.9% transmissions at the NewSUBARU facility to investigate how the original Poisson distribution of the pulsed photons is modified after passing through thick-target materials. We present a well-prescribed method of determining the number of incident photons within 3.5% accuracy based on the response of the NaI(Tl) detector to the pulsed photon beams.

Sn, 
Sn, 
Sn, 
Sn, and 
Sn near neutron threshold with quasi-monochromatic laser-Compton scattering -rays. A systematic analysis of the present photoneutron data and existing neutron-capture data is made using the -ray strength function on the basis of the HFB+QRPA model of E1 strength supplemented with a pygmy dipole resonance, which was deduced from a previous study on 
Sn and 
Sn. Radiative neutron capture cross sections for two radioactive nuclei, 
Sn and 
Sn, are deduced through the -ray strength function method.

Times Cited Count：2 Percentile：20.16(Physics, Multidisciplinary)The photo-nuclear cross section of Se isotopes (
Se, 
Se, Se, 
Se) were measured with laser-Compton scattering (LCS) -rays to supply fundamental data for the estimation of the inverse reaction cross sections, i.e., the Se(,) Se cross section. An enriched Se isotope samples were irradiated with LCS -rays whose maximum energy was varied from each near neutron separation energy to 16.0 MeV. The energy distributions of LCS -rays were precisely determined using a high-resolution high-energy photon spectrometer (HHS). Emitted neutrons were detected by a high efficiency 4-
He detector. The excitation function of the photo-nuclear cross section of Se isotopes were determined for the energy range form each near neutron separation energy to near 16.0 MeV. The energy point corresponding to each cross section was deduced using the accurately determined energy distribution of LCS -rays.

In this project, we constructed the pulsed neutron beamline that was aimed to obtain neutron capture cross-sections of long-lived fission products and minor actinides accurately. The energy spectra, spatial distributions, and pulses of the beam were studied by measurements and simulation calculations, and they were found to be consistent with those of the beamline design. In this paper, we present the overview of the project and the properties of the neutron beam provided by this beam line.
