The level structure of <SUP>172</SUP>Dy has been investigated for the first time by means of decay spectroscopy following in-flight fission of a <SUP>238</SUP>U beam. A long-lived isomeric state with T<SUB>½</SUB>=0.71(5) s and K<SUP>π</SUP>=8<SUP>-</SUP> has been identified at 1278 keV, which decays to the ground-state and γ-vibrational bands through hindered electromagnetic transitions, as well as to the daughter nucleus <SUP>172</SUP>Ho via allowed β decays. The robust nature of the K<SUP>π</SUP>=8<SUP>-</SUP> isomer and the ground-state rotational band reveals an axially-symmetric structure for this nucleus. Meanwhile, the γ-vibrational levels have been identified at unusually low excitation energy compared to the neighboring well-deformed nuclei, indicating the significance of the microscopic effect on the non-axial collectivity in this doubly mid-shell region. The underlying mechanism of enhanced γ vibration is discussed in comparison with the deformed Quasiparticle Random-Phase Approximation based on a Skyrme energy-density functional.

<P>We report a novel soft chemical synthesis method, water assisted solid state reaction (WASSR) method. This method is very simple and can synthesize many ceramic materials just by storing or mixing raw materials added a small amount of water in a reactor at low temperature below 373 K. For example, well-crystalline SrMoO4 was obtained using the WASSR method.</P>

<P>SmBCO and YBCO coated conductors (CC) showed different critical current, I<SUB>c</SUB> degradation behavior with strain showing different I<SUB>c</SUB> peak position under self field. Strain effect on I<SUB>c</SUB> under magnetic field in REBCO CC tapes was investigated in order to measure and to describe its tolerance and degradation behavior. Katagiri-type tensile testing apparatus was adopted in which magnetic field was applied parallel to the c-axis of coating film using 10 T superconducting magnet at 77 K. Both strain gauge and Nyilas double extensometers were used to measure the strain. In all the REBCO CC tapes investigated, I<SUB>c</SUB>(ε, B) strongly depends on magnetic field and their degradation behavior depends on the kind of HTS film and fabrication technique adopted. Differently with YBCO CC tapes, SmBCO CC tapes showed increasing I<SUB>c</SUB> strain sensitivity with increasing magnetic field at 77 K and the irreversible strain limit was magnetic field independent over the entire field range studied.</P>
Phase Diagram and Transport Properties of Y1−xNdxCo2 Pseudo-binary Alloys

The electrical resistivity and the thermopower S of pseudo-binary Y1−xNdxCo2 alloys have beenmeasured at temperatures from 2 to 300 K under pressures up to 3.5 GPa. NdCo2 is a ferromagnetwith a Curie temperature TC of 98 K. In the ferromagnetic phase, it undergoes a 4f spin-reorientationtransition at TR = 40 K. At this transition, the easy direction of 4f magnetization is changed from[100] at temperatures above TR to [110] below TR. The system phase diagram TC(x, P) and TR(x, P)is inferred from the temperature dependencies of the electrical resistivity and the thermopower. The Curie temperature of the alloys, TC decreases with decreasing Nd concentration x and vanishesaround xc = 0.3. Above xc, the Curie temperature decreases with increasing pressure. The spinreorientationtemperature weakly depends on the composition and on the pressure until it mergeswith TC. There is a large region of the phase diagram, partly overlapping with the ferromagneticphase, where the cobalt 3d electron system is non-uniformly magnetized due to spatial fluctuationsof the 4f-3d exchange field related to a random distribution of Nd 4f magnetic moments over the Rsublattice. In this region, large static 3d magnetic fluctuations govern the electronic transport.

<P><B>Abstract</B></P> <P>The neutron-rich isotopes of palladium have attracted considerable interest in terms of the evolution of the N = 82 neutron shell closure and its influence on the <I>r</I>-process nucleosynthesis. In this Letter, we present the first spectroscopic information on the excited states in <SUP>125</SUP>Pd<SUB>79</SUB> and <SUP>127</SUP>Pd<SUB>81</SUB> studied using the EURICA <I>γ</I>-ray spectrometer, following production via in-flight fission of a high-intensity <SUP>238</SUP>U beam at the RIBF facility. New isomeric states with half-lives of 144(4) ns and 39(6) μs have been assigned spins and parities of ( 23 / <SUP> 2 + </SUP> ) and ( 19 / <SUP> 2 + </SUP> ) in <SUP>125</SUP>Pd and <SUP>127</SUP>Pd, respectively. The observed level properties are compared to a shell-model calculation, suggesting the competition between proton excitations and neutron excitations in the proton-hole and neutron-hole systems in the vicinity of the doubly magic nucleus <SUP>132</SUP>Sn.</P>
Preparation of copper nanoparticles with an organic coating by a pulsed wire discharge method
K. Murai,Y. Watanabe,Y. Saito,T. Nakayama,H. Suematsu,W. Jiang,K. Yatsui,심광보,코이치니하라 한양대학교 세라믹연구소 2007 Journal of Ceramic Processing Research Vol.8 No.2
In the pulsed wire discharge method, a coating technique to prepare metal nanoparticles covered with organic matter has been investigated. Copper nanoparticles covered with organic matter have been successfully prepared by evaporation of a copper wire in an oleic acid vapor/mist. The thickness of the coating layer was a few nanometres. The median diameter of the powder was 25 nm, and became 10 nm smaller than that without the coating because of the inhibition of particle growth by the formation of the coating. From phase identification by transmission electron microscopy and X-ray diffraction analysis, it was found that the copper nanoparticles have been passivated and have not been oxidized in over 2 months.
