Lead-Bismuth Eutectic (LBE) is used as a spallation neutron target and coolant materials of Accelerator Driven System (ADS), and many kinds of elements are produced as spallation products. It is important to evaluate the release and transport behavior of the spallation products in the LBE. The inventories and the physicochemical composition of the spallation products produced in LBE have been investigated for an LBE loop in the ADS Target Test Facility (TEF-T) in J-PARC. The inventories of the spallation products in the LBE were estimated using the PHITS code. The physicochemical composition of the spallation products in the LBE was calculated using the Thermo-Calc code under the conditions of the operation temperatures of LBE from 350$$^{circ}$$C to 500$$^{circ}$$C and the oxygen concentrations in LBE from 10 ppb to 1 ppm. The calculation showed that the 5 elements of Rb, Tl, Tc, Os, Ir, Pt, Au and Hg were soluble in LBE under the all given conditions and any kinds of compound were not formed in LBE. It was suggested that the oxides of Ce, Sr, Zr and Y were stable as CeO$$_{2}$$, SrO, ZrO$$_{2}$$ and Y$$_{2}$$O$$_{3}$$ in the LBE.

We performed a benchmark study for 58 cases using the recent version 2.88 of the Particle and Heavy Ion Transport code System (PHITS) in the following fields: particle production cross-sections for nuclear reactions, neutron transport calculations, and electro-magnetic cascade. This paper reports details for 22 cases. In cases of nuclear reactions with energies above 100 MeV and electro-magnetic cascade, overall agreements were found to be satisfactory. On the other hand, PHITS did not reproduce the experimental data for an incident proton energy below 100 MeV, because the intranuclear cascade model INCL4.6 in PHITS is not suitable for the low-energy region. For proton incident reactions over 100 MeV, PHITS did not reproduce fission product yields due to the problem of high-energy fission process in the evaporation model GEM. To overcome these inaccuracies, we are planning to incorporate a high-energy version of the evaluated nuclear data library JENDL-4.0/HE, and so on.

The antiferromagnetic ordered phase below $$T_{rm MI}$$ = 16.5 K and the unresolved intermediate phase between $$T_{rm MI}$$ and $$T^*$$ (= 14 K) in SmRu$$_4$$P$$_{12}$$ have been studied by resonant and nonresonant X-ray diffraction. In the intermediate phase, nonresonant Thomson scattering with $$q$$ = (1,0,0) is induced by applying a magnetic field. This phenomena is caused by atomic displacements reflecting the charge order in the $$p$$ band, as predicted theoretically. Simultaneously, the antiferromagnetic moment of Sm is enhanced along the field direction, which is considered to reflect the staggered ordering of the $$Gamma_7$$ - $$Gamma_8$$ crystal-field states. The present results show that the orbital-dependent $$p$$ - $$f$$ hybridization in association with the nesting instability in the $$p$$ band gives rise to the unconventional charge order similarly with PrRu$$_4$$P$$_{12}$$ and PrFe$$_4$$P$$_{12}$$.

$$^{29}$$Si-NMR Study of antiferromagnet CeRh$$_2$$Si$$_2$$ with a tetragonal ThCr$$_2$$Si$$_2$$-type structure has been performed using single crystals. The Knight shifts along the $$a$$ and $$c$$ axes have been measured as a function of temperatures in the paramagnetic state. At ambient pressure, the Knight shifts show the Ising-type anisotropy along the $$c$$ axis, which is similar to the magnetic susceptibility. The hyperfine coupling constants for $$^{29}$$Si along the $$a$$ and $$c$$ axes have been determined from Knight shifts versus static susceptibility plots.
