Monte-Carlo Study of Bound States in a Few-Nucleon System - Method of Continued Fractions -
We propose a new type of Monte-Carlo method which enables us to study the
excited state of many-body systems.Comment: ReVTeX: 25 pages, 10 Postscript figures,2 tables, uses epsf.sty:to be

Microstructure and mechanical properties of hip-consolidated Rene 95 powders
The effects of heat-treatments on the microstructure of P/M Rene 95 (a nickel-based powder metal), consolidated by the hot-isostatic pressing (HIP), were examined. The microstructure of as-HIP'd specimen was characterized by highly serrated grain boundaries. Mechanical tests and microstructural observations reveal that the serrated grain boundaries improved ductility at both room and elevated temperatures by retarding crack propagation along grain boundaries
Superconducting gap of overdoped Tl2Ba2CuO6+d observed by Raman scattering
We report Raman scattering spectra for single crystals of overdoped
Tl2Ba2CuO6+d (Tl-2201) at low temperatures. It was observed that the
pair-breaking peaks in A1g and B1g spectra radically shift to lower energy with
carrier doping. We interpret it as s-wave component mixing into d-wave,
although the crystal structure is tetragonal. Since similar phenomena were
observed also in YBa2Cu3Oy and Bi2Sr2CaCu2Oz, we conclude that s-wave mixing is
a common property for overdoped high-Tc superconductors.Comment: 8 pages, 3 figures, proceedings of SNS200

Phenomenology of the little bang
I review recent selected developments in the theory and modeling of
ultrarelativistic heavy-ion collisions. I explain why relativistic viscous
hydrodynamics is now used to model the expansion of the matter formed in these
collisions. I give examples of first quantitative predictions, and I discuss
remaining open questions associated with the description of the freeze-out
process. I argue that while the expansion process is now well understood, our
knowledge of initial conditions is still poor. Recent analyses of two-particle
correlations have revealed fine structures known as ridge and shoulder, which
extend over a long range in rapidity. These correlations are thought to
originate from initial state fluctuations, whose modeling is still crude. I
discuss triangular flow, a simple mechanism recently put forward, through which
fluctuations generate the observed correlation pattern.Comment: 10 pages, plenary talk at the International Nuclear Physics

Cluster-orbital shell model approach and developments for study of neutron-rich systems
We develop an m-scheme approach of the cluster-orbital shell model (COSM). By using the Gaussian as the radial part of the basis function, components of the unbound states are correctly taken into account. We apply the m-scheme COSM to oxygen isotopes and study the energies and r.m.s.radii
