Times Cited Count:38 Percentile:87.07(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.

The number of research reactors in the world is decreasing because of their aging. However, the planning to introduce the nuclear power plants is increasing in Asian countries. In these Asian countries, the key issue is the human resource development for operation and management of nuclear power plants after constructed them, and also the necessity of research reactor, which is used for lifetime extension of LWRs, progress of the science and technology, expansion of industry use, human resources training and so on, is increasing. From above backgrounds, the Neutron Irradiation and Testing Reactor Center began to discuss basic concept of a multipurpose low-power research reactor for education and training, etc. This design study is expected to contribute not only to design tool improvement and human resources development in the Neutron Irradiation and Testing Reactor Center but also to maintain and upgrade the technology on research reactors in nuclear power-related companies. This report treats the activities of the working group from July 2010 to June 2011 on the multipurpose low-power research reactor in the Neutron Irradiation and Testing Reactor Center and nuclear power-related companies.

Times Cited Count:43 Percentile:89.94(Physics, Nuclear)Photoneutron cross sections were measured for 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.
