In-NQR measurements of CePtIn were made. We succeeded in identifying at least two of the four In sites. Temperature dependent measurement of the spin lattice relaxation time was carried out. In the superconducting state. There was a strong temperature dependence of the spin lattice relaxation time. Discuss superconducting symmetry.

Study for radiation DNA damage is very important to understand initial factors for mutation and cancer inductions. From much investigation for DNA base damage, oxidative and reductive base damage are much detected, rather than abasic damage originated from molecular dissociation. To reveal the reason, the dynamic behavior of secondary electrons was analyzed using semi-classical dynamic Monte-Carlo code developed in this study. From the results, it was found that the abasic damage was slightly produced because 15% of electronic excited electrons were formed in liquid water. The results will contribute to analyses for the radiation DNA damage, and will provide us a significant fundamental insight for formation of deleterious complex clustered DNA damage leading further biological effects.

We have studied uranium ferromagnetic superconductivity of the actinide 
electrons system. The applicability of the spin fluctuation theory to the actinide system were investigated. In the previous JPS meeting, we reported the result of the magnetization measurement on uranium ferromagnetic superconductors UGe. In this talk, we present the generalized Rhode-Wohlfarth relation in UGe and spin fluctuation parameters in URhGe-UCoGe system.

There are many polyvalent liquid metals with complex structure which cannot be reproduced by random packing model. To explain such complexity, coexistence of metallic and covalent bonds, dynamic model of short-lived covalent bonds, and quasi-crystal model where Peierls distortion still remains even in liquid phase have been proposed from structure analyses and theoretical calculations. To obtain concrete picture experimentally for complex structure, it is indispensable to measure dynamic structure with precise statistical accuracy. We performed inelastic neutron scattering of liquid bismuth by using AMATERAS installed at MLF in J-PARC and deduced its time-space correlation function. We got evidence that structure of Peierls distortion remains even in liquid by evaluating difference in relaxation time at specific atomic distances characterized by double layered structure.

Lead titanate, PbTiO, has a tetragonal structure having a large c/a ratio at room temperature. A phase transition to the paraelectric phase at 490
C, structural changes to cubic. However, just above the transition point to the paraelectric phase, the phonon modes of the still ferroelectric is observed. Therefore, spontaneous polarization using a sample of reversible high quality, perform high-energy X-ray diffraction experiments were subjected to structural analysis in a wide temperature range from room temperature to 800C. Short range order structure analysis and atomic two pairs distribution function (atomic pair-distribution function, PDF) was performed using. A comparison local structures at room temperature of the observed local structure and relaxor Pb (Mg

)O (PMN) with 800C of PbTiO, network structure similar to the relaxor PMN is present in the high temperature phase of PbTiO It is considered to have.

We will report the phonon dynamical study of a polycrystalline NaI by using the dynamical structure factor in real-space 
transformed from the inelastic neutron scattering (INS) data. Our study has suggested the possibility that a large amount of INS data which were previously obtained can be effectively reused.

-US is known as a narrow-gap semiconductor. The magnetoresistance in this compound is extremely large but anisotropic. To obtain microscopic view of the magnetism, we have carried on S-NMR study. We will discuss the magnetic properties in this system to show the recent NMR results.
