Times Cited Count：13 Percentile：48.43(Materials Science, Multidisciplinary)Metastable phases in aluminum alloys are the primary nano-scale precipitates which have the biggest contribution to the increase in the tangible mechanical properties. The continuous increase in hardness in the 7xxx aluminum alloys is associated with the phase transformation from clusters or GP-zones to the metastable 
phase. The transformation which is structural and compositional should occur following the path of the lowest activation energy. This work is an attempt to gain insight into how the structural transformation may occur based on the shortest route of diffusion for the eventual structure to result in that of phase. However, for the compositional transformation to occur, the proposed mechanism may not stand, since it is a prerequisite for the atoms to be at very precise positions in the aluminum lattice, at the very beginning of structural transformation, which may completely differ from that of the GP-zones atomic arrangements.

The expert group (EG) on Uncertainty Analysis for Criticality Safety Assessment (UACSA) was established within the OECD/NEA Working Party on Nuclear Criticality Safety in December 2007 to promote exchange of information on related topics; compare methods and software tools for uncertainty analysis; test their performance; and assist in selection/development of safe and efficient methodologies for validation of criticality computations. At the current stage, the work of the group is focused on approaches for validation of criticality calculations. With the diversity of the approaches to validate criticality calculations, a thorough description of each approach and assessment of its performance is useful to the criticality safety community. Developers, existing and potential practitioners as well as reviewers of assessments using those approaches should benefit from this effort. Exercise Phase I was conducted in order to illustrate predicting capabilities of criticality validation approaches, which include similarity assessment, definition of 
bias and bias uncertainty, and selection of benchmarks. The approaches and results of the exercises will be thoroughly documented in a pending state-of-the-art report from the EG. This paper provides an overview of current and future activities for the EG, a summary of the participant-contributed validation approaches, and a synthesis of the results for the exercises.

There have been long debate on the usefulness of in-situ tracer experiment, because the difference in temporal scale, where in-situ tracer experiments are generally conducted for the period of a few days to several months with high velocity to recover the tracers, whereas safety assessment requires more than ten thousand years with much slower velocity. This paper addresses the issue by comparing breakthrough curves for safety assessment conditions (long-term, slow velocity) with and without calibration to in-situ tracer experiment called STT-1b test at the Aspo Hard Rock Laboratory in Sweden. Authors newly developed a conceptual model of internal structure of fracture, which explicitly addresses fault gouge, coating minerals, altered zone and intact rock, since especially fault gouge has high porosity and likely to affect the tracer migration behavior. The result was that calibrated model showed much tighter distribution of breakthrough curve statistics indicating the constraining power of in-situ tracer experiment.

-decay experiment of Na which was performed at National Superconducting Cyclotron Laboratory in Michigan State University. The 2.1 MeV state proposed previously was denied because the corresponding 
ray is found to be located elsewhere. New level scheme is proposed and compared with the Monte Carlo shell model by JAEA. The ground state of Na appears to be a negative parity states from the decay pattern and the calculation. We suggested that the configuration of the states which are strongly populated via the decay is 3p-3h, since the ground state of the parent nucleus is most likely 2p-3h character.

We argue that these anomalies are due to an orbital ordering of Ru 
electrons, with a strong coupling among three degrees of freedom: orbital, spin, and lattice. Our work provides a unique example of the spontaneous formation of Haldane system with an insight into the intriguing interplay of different degrees of freedom.

was studied. No significant difference of degradation was observed between p- and n-substrates irradiated with 2MeV-alpha micro beam. The decrease in IBCC shows a good agreement with the calculation using non ionizing energy loss (NIEL). As a result of ion luminescence and ultra violet photo luminescence, the level of 2.32 eV was observed.

m on n- or p-type 6H-SiC were fabricated using the evaporation of Al, Ni, and Au. To study the radiation damage of diodes, the 2MeV-He ion micro beam with a diameter of 1 m was irradiated from 10

10 m area. As the result, the value of IBIC decreased with increasing the dose of 2 MeV-He. This indicates that the charge collection decreases by the recombination centers introduced by irradiation.
