By neglecting certain terms in the Hamiltonian (of importance only in the immediate neighbourhood of the threshold energy) we are able to write an exact expression for the photoemission intensity which involves the standard time inverted LEED state and broadened hole-states. If inelastic extrinsic losses are neglected…
Isothermal demixing process of binary polymer mixtures of SBR (styrene–butadiene random copolymer) and polybutadiene at deep quench depths was investigated by time-resolved light scattering technique. The results indicated that the systems undergo extremely slow spinodal decomposition of the type as adequately charact…

The crystal structures of ZrO 2 and HfO 2 (P2 1 /c) were refined in detail from X‐ray powder diffraction data. The precision obtained for the atom positions for both compounds is comparable to that of previous single‐crystal work.

Calculations of bulk and surface defect energies were used to develop a model of the grain structure of doped BaTiO 3 , Segregation processes are expected as a consequence of thermo‐dynamic and kinetic factors and result in the development of n‐i‐n junctions at intergranular contacts, thus leading to the observed PTCR…
The relationship between short-range icosahedral order in metallic glasses and long-range order in icosahedral crystals is explored. Metallic-glass structure factors are assumed to describe liquids in metastable equilibrium just above the glass transition. A density-functional mean-field theory is then used to search…
The structure and properties of thin amorphous carbon films are critically dependent upon the preparation conditions. Hydrogenated amorphous carbon films, prepared by both ion beam sputtering and glow discharge techniques, have been investigated by solid-state 13C magic angle spinning nuclear magnetic resonance measur…

An alternative and somewhat systematic definition of the vector spherical harmonics, in analogy with the commonly used scalar spherical harmonics, is presented. The new set of vector spherical harmonics satisfies the properties of orthogonality and completeness, and is compared with other existing definitions of vecto…

The detailed study of electrical properties in group III impurity doped ZnO thin films prepared by rf magnetron sputtering is described. The resistivity is lowered by doping of B, Al, Ga and In into ZnO films. The characteristic features of ZnO films doped with group III elements except for B are their high carrier co…
We show that the optical phase-conjugated reflectivity from silver and gold colloids is enhanced by several orders of magnitude. The reflectivity on resonance is comparable with that of CS(2) for metal-particle volume concentration of a few parts in 10(6). We trace this enhancement to the nonlinearities of the electro…
