The nuclear structure and decay data of A=126 nuclides are evaluated to update this part of Evaluated Nuclear Structure Data File (ENSDF). There are various kinds of experiments such as beta-decay, neutron reaction and charged particle reaction for 16 isobars from 
Rh to Nd. By evaluating these experimental data, recommended values for energies and intensities of levels and 
-rays were given. Also, spins and parities of these levels were evaluated. In my talk, some examples of inconsistencies between data will be presented. Status of the international network of evaluators will also be reported.

Extension of Geant4 toolkit for -ray non-destructive assay of isotopes is reported. In the extension, nuclear resonance fluorescence (NRF), a process to identify and assay isotope of interest, has been implemented. We have also implemented elastic scattering, background of NRF, as a sum of three different processes, Rayleigh scattering, nuclear Thomson scattering and Delbruck scattering. We present the result of the extension with simulation examples.

Ferromagnetism is incompatible in general with superconductivity (SC) with singlet spin pairs, since a strong exchange field in ferromagnetic state forces the spin pairs to align in the same direction. In contrast, fluctuation of ferromagnetic moments has been supposed to create a binding force between quasi-particles with triplet spin. Such an unconventional spin-triplet state, mediated by ferromagnetic fluctuations, is now expected to be realized in a family of uranium based compounds, UGe
, URhGe and UCoGe, so far the only fully established examples of ferromagnetic superconductors in which uniform SC is realized deep inside the ferromagnetic states. To elucidate the mechanism of this exotic SC, we have prepared a URhGe single crystal and performed nuclear magnetic resonance (NMR) experiments.

In URuSi, superconductivity occurs at 
=1.5 K under so-called "hidden order" phase with the transition temperature of 
17.5 K. It is a fascinating subject to investigate the detail of the superconducting (SC) state in the "hidden order" phase and the relationship between the superconductivity and the "hidden order". Therefore we have performed 
Si NMR measurements on single crystalline URuSi. We have observed clear decrease in Si Knight shift in the SC state along the magnetic easy axis, while there was no detectable change in in-plane Si Knight shift. Possible SC symmetry and the mechanism of superconductivity in URuSi will be discussed.

In the life science at the molecular level, measurement analysis technique plays a key role. In late years the technology development is remarkable, and various measurement technique is developed, but know a rare biomolecular change (structure and dynamics) by other measurement technique in the neutron. Neutron technique in bioscience is powerful tool for thermal properties such as glass transition as well as structural analysis. In addition, the life sciences are related with not only physical studies such as the elucidation of the life phenomenon but also the technologies such as medicine, a pharmacy, the agriculture closely.

In the J-PARC RCS, the multi-turn charge-exchange injection scheme is adopted. In addition, the painting injection method which arranges the injection beam on the wide phase-space area during the multi-turn injection has been performed to expand the circulating beam. This method is essential to mitigate the beam loss caused by the particles scattered at the charge-exchange foil and the space charge force. In the RCS, the residual gas ionization profile monitor (IPM) which is nondestructive 1D transverse profile monitor is adopted for the observation and optimization of the painting scheme. The IPM mainly consists of the divided electrodes generating the external electric field and the detection unit. For the profile measurement, the residual gas ionized by the beam is transported to the detection unit by the external transverse electric field and amplified by the Multi-Channel Plate (MCP) as the electron. After that, these electrons are detected and the 1D distribution is reconstructed. However, the distribution cannot be measured during painting injection because the noise increases and hides the signal. To solve this problem, we investigated the source of this noise and examined measures. To compare the simulation and the noise measurement results, we identified the cause of the noise as the electric field from the beam. Therefore, we developed additional electrode component to shield that field based on the simulation result. As a result, the noise was reduced to be 30 to 50 %. In addition, the change of 1D beam profile was observed during painting for the first time though the beam intensity was low of 7 kW.

SiO glass consists of SiO
tetrahedra which are mutually connected and forms the many-membered ring. Thus, the glass has large void in its structure, and therefore marked densification is expected under pressure. Actually, it is known that the density increases by 20% on compression to 8 GPa, accompanying the change in the intermediate range order. The density goes back to the original value by decompression, whereas the high-density state is retained once the structure is relaxed by being heated at high pressures. In this study, the mechanism of the densification at room-temperature and high-temperature has been investigated by in-situ high-pressure neutron diffraction at high-pressure neutron beamline PLANET in J-PARC, coupling with previously reported X-ray data. We have constructed 3-dimensional atomic arrangements by Reverse Monte Carlo simulation. In this talk, the mechanism of densification at room-temperature and high-temperature and their differences will be discussed based on the obtained atomic arrangements.
