Times Cited Count:45 Percentile:87.7(Physics, Multidisciplinary)The neutron-rich nucleus Ar is produced by the fragmentation reactions of Ca, Sc, and Ti at the RIBF facility in RIKEN, and its deexcited rays are observed for the first time. The first level in Ar is identified to lie at 1178(18)keV from the most intense -ray spectra. This experimental data, together with the systematics of the levels for surrounding nuclei, is analyzed with large-scale shell-model calculations. Consequently, the sub-shell gap in Ar is equivalent to that of Ca, thus making the level in Ar higher than that of Ar. The shell-model calculation also predicts that the sub-shell gap enhances in going from Ca to Ar, which will be verified by forthcoming experiments for Ar.

Times Cited Count:22 Percentile:80.29(Instruments & Instrumentation)The neutron powder diffraction data of the apatite-type La-silicate LaSiO was measured at 10 K and the Rietveld refinement on the basis of hexagonal P6/m was successfully carried out. The obtained cell parameters were =0.971297(7) nm, and = 0.717950(6) nm. On the Rietveld refinement supported by maximum entropy method, the interstitial oxygen positions show randomly distribution around La2 site, and they may give the driving-force of high ionic conductivity to the main ionic conduction site O4.

Times Cited Count:24 Percentile:67.72(Chemistry, Physical)A novel synthesis method of lanthanum silicate apatite was developed by a sol-gel method using an aqueous solution system. The processes of apatite phase formation were investigated by XRD and TG-DTA. Lanthanum dioxide carbonate was found in the sample below 873 K and lanthanum silicate apatite was formed above 1073 K. It was founded that the profiles of powder XRD and neutron diffraction could be refined by the oxy-apatite structure with the space group 6/.

A junction space between a super deep shaft and horizontal drifts forms a 3-dimensional geo-structure, which would take a complicated mechanical behavior during a junction excavation. However, a quantitative design method for a deep junction has not yet established. In order to examine a collapse mechanism of super deep shaft junction, we have conducted literature surveys and interview studies concerned with a collapses. Considering the results of investigations with reviews of intellectuals, the collapse mechanism depends on both a construction procedure of shaft junction and a geological condition. On the other hand, where a deep junction intersects faults and/or fractures with a large angle, a collapse called taka-nuke may occur and a numerical studies that can simulate a practical rock mass behavior around a shaft junction should be carry out. We demonstrate finite difference method is most adequate for these simulations with intellectual review.

Conduction properties of oxide ions and crystal structure refinement of La(SiO)O have been made by A.C.-impedance, electro-motive force of oxygen concentration cell, X-ray and neutron diffraction methods using the sample fabricated by the sol-gel method. The crystal structure of the sample can be refined by structural model with 6/ space group. Oxide ion conductivity is found to be predominant in wide oxygen partial pressure and temperature range based on the conductivity and electro-motive force measurements.
