T-dependence and anisotropy of Knight shift and spin-lattice relaxation time T1 of In-NMR have been determined in heavy fermion superconductor CeIrIn. Knight shift and T1 show a strong anisotropy. Knight shift versus static susceptibility plot is non-linear at low temperatures, indicating that the hyperfine coupling depends on temperature. The origin of hyperfine interaction and anisotropy of spin fluctuations will be discussed.

Recently discovered iron-arsenide new superconductor has attracted considerable attraction. Within a few months the transition temperature (
) exceeded 50 K in some related compounds, and the possible novel physics as well as higher- are expected. At the early stage, calculations of phonon properties appeared and suggested that the superconductivity in these materials are not phonon mediated. However, the experimental verification is crucial. We carried out inelastic X-ray scattering on some powder as well as single samples, and found pronounced softening of the Fe-As modes compared to LDA-based phonon calculations. However, further investigation on single crystals showed the spectra are found to agree much better with calculations of the magnetic parent material, which has orthorhombic symmetry, than those using a tetragonal structure like the real superconducting compounds.

The incomplete fusion reaction, in which a part of a projectile is absorbed by a target, proceeds through a compound process. There is a long history of the study of the fusion reaction. However, the incomplete fusion process is not sufficiently well understood. The process contributes significantly in the reaction involving weakly bound nuclei, and the understanding of the reaction mechanism is required. Since a weakly bound nucleus, such as deuteron, breaks up easily in the reaction, the model taking into account the breakup process is required for the analysis. We extended the Continuum-Discretized Coupled-Channels (CDCC) method, and applied to the analysis of incomplete fusion reaction. In the present paper, we show calculated results of incomplete fusion cross section in the deuteron induced reaction on 
Li target, and discuss the importance of the process.

Hierarchical structures of F-actin, an anionic polyelectrolyte, and PDMAPAA-Q, a synthetic linear cationic polyelectrolyte (polycation), complexes in KCl salt solutions have been examined over a wide range of length scales from nanometer to micrometer using a combination of ultra-small-angle neutron scattering technique and fluorescence microscopy. We found hierarchical condensation of actin/polycation complex composed of a superbundle of 10 micrometer, protobundle of 100 nanometer, and protofilament (F-actin) of nanometer. These structures are largely influenced by salt concentrations. With increase of salt concentration superbundle structure changes from globular to extended states, simultaneously, the regularity of F-actin inside the protobundle increased and protobundle size increased about ten times larger. Further increase of salt concentration brings the protobundle disassemble to single F-actin.
