NMR measurements in a single crystalYbRhSi are reported. Previously, the results for H//a have been reported, this time results for H//a are presented. As well as the case for H//c, the coexistence of Fermi and non-Fermi liquid states is observed for H//a, however, the T-and H-dependences are different from those for H//c.

Cu has being attracting attention as a potential candidate for radiopharmaceutical. A high-purity Cu can be isolated from an irradiated 
ZnO using fast neutrons generated via 
C(d,n) reaction with only a few RIs as side products. This study was aimed at achieving a higher purity for the final Cu by separating 
Ni amongst other side products. As a result Cu free from Ni was obtained with high radionuclide purity with minimum loss of time during the separation.

When non-axisymmetric magnetic perturbations are imposed in axisymmetric tokamaks, broken axisymmetry induces the neoclassical viscosity, and affects momentum transport and resulting plasma rotation profiles. In this work, we estimate the neoclassical toroidal viscosity using full-f gyrokinetic simulations, and verify calculation methods and obtained results. We discuss the parameter dependency of the neoclassical toroidal viscosity in the presence of small resonant magnetic perturbations, based on comparisons against analytic theories and neoclassical transport codes.

We show that electric voltage generation (spinmotive force) from magnetic bubble arrays subject to a magnetic field gradient. The formula for the induced voltage is derived and whereby a new method is proposed for determining the magnitude of the phenomenological parameter 
that measures non-adiabaticity of current-induced magnetization dynamics. This spinmotive force opens up a door for developing a new type of spintronics devices relying on the magnetic field gradient.

We report the result from the theoretical study based on the numerical diagonalization and the finite-size scaling analysis, on the quantum phase transition which occurs when the ratio of the rung coupling, the leg coupling and the ring exchange interactions is varied, in the S=1/2 three-leg spin tube.

We numerically investigated the dynamical susceptibility of the S=1/2 trimerized quantum spin chain. In order to solve the mechanism of the special feature, which is characteristic of the composite spins different from the single S=3/2, observed in the previous high frequency ESR measurement by Prof. Ajiro, we will report the numerical result of the external field dependence and the temperature dependence of the dynamical susceptibility.

"Gaussian Mixture Learning" is a well-known method to infer the probability distribution from a set of coordinate data it generated. In this study, a mixture distribution is composed of complex mixture ones, and generates the data we observe. Then, we estimate "the mixture ratio among mixture distributions" and "the ratio and parameters of elemental distributions in each mixture" from the data. Our approach is based on the hierarchical formulation of Gaussian Mixture Learning. We discuss and report the effectiveness of this learning method, applying it to the estimation problems of nuclides' components in 
-ray energy spectra.

Superconducting detectors allow definite tools to explore science frontiers, such as neutron radiography, X-ray spectroscopy, and quantum cryptography. In this paper, we study a thermal-activation character of the kinetic inductance, towards revealing the basic mechanism in a kinetic-inductance-based superconducting detectors. We examine the current-dependence of the kinetic inductance in superconducting wires using the Ginzuburg-Landau approach with thermal fluctuations. Our theory predicts a non-monotonic current-dependence of the kinetic inductance when the thermal fluctuations predominate the behaviors of the superconducting phase. This result comes from phase-slip centers relevant to thermally-activated processes. Moreover, we show that the present approach qualitatively reproduces the experiment by Annunziata et al.

In the ELFIE laser facility at LULI, the dynamics of laser-produced blast waves in cluster targets has been investigated by means of the optical probing (interferometry and Schlieren imaging) and the proton probing. Interferometry and Schlieren imaging have provided a spatially and temporally resolved mapping of the electron density and density gradient distributions. In addition, spatially and time-resolved proton probing has provided mapping of the electric fields and charge density distributions in the plasma in the initial phase of plasma expansion and shock formation.

PLANET is the beamline dedicated for the high-pressure experiments. The operation has been started at JFY 2013, and now many users are coming to use. In this talk, we introduce the current state of the PLANET and the example of the structure analysis of disordered materials. PLANET adopted the double staged compression system of the multi anvil 6-6, and enables the data collation at 10 GPa and 2000 K. To extend accessible PT range, we newly introduce another compression system of multi-anvil 6-8, and succeeded in generating 16 GPa and 1273 K. In addition, the PLANET is designed so that we can analyze the structure of liquid under pressure. In the analysis, the program for liquid analysis developed at BL21 NOVA is used. Here, we briefly introduce the reliability of the results and the pressure evolution of the silica glass.

In this study, CeO and NiO were irradiated with Au ions in the energy range of 200-340 MeV at oblique incidence. Observation of as-irradiated samples by transmission electron microscope (TEM) shows that hillocks are created not only at the wide faces but also at the crack faces of thin samples. Since the hillocks created at the crack faces can be imaged by TEM, their shape and crystallographic features are revealed by TEM. From the images of hillocks created at the crack faces, many of the hillocks are found to be spherical for ion-irradiated CeO. For ion-irradiated NiO, atomic-scale steps are found to be created at the top surface of the hillocks. We present first experimental evidence that hillocks created for both oxides irradiated with swift heavy ions have a crystal structure whose lattice spacing and orientation coincide with those of the matrix.
