Neutron data for total and capture cross sections were evaluated on 160Dy, 161Dy, 162Dy, 163Dy, and 164Dy up to 20 MeV. The resolved resonance parameters were adopted from the Mughabghab compilation, but one bound level resonance for each isotope except 162Dy was invoked to reproduce the reference thermal cross sections. The average resonance parameters for s-wave neutrons were obtained from th...

An increasing part of the semiconductor device community is using SOI wafers for the fabrication of modern CMOS generations (FINFET [1], Schottky barrier transistors [2], (bio-) sensor applications, optical devices and also as test vehicles to study the fundamental properties of 1D and 2D silicon structures. For SOI thicknesses below the Debye length it becomes interesting to study metal-Si con...

The photoconductive excitation spectrum of GaP:N (ZnTe) diodes was measured irradiating the samples from pand n-side unter forward and reverse bias conditions. The ionization thresholds of S and Te donors as well as transitions from their ground states to excited bound levels with subsequent ionization by the electric field could be seen. The observed minima in the continuum above the ionizatio...

Abstract. In present work the effective singlet-triplet model for CuO2-layer in the framework of multiband p-d model of strongly correlated electrons is obtained. The resulting Hamiltonian has a form of generalized singlet-triplet t-t’-J model for p-type superconductors and form of usual t-t’-J model for n-type superconductors. In the mean field approximation in X-operator representation we der...

Scattering of ortho positronium (Ps) by cesium and rubidium atoms has been investigated employing a three-Ps-state coupled-channel model with Ps(1s,2s,2p) states using a time-reversal-symmetric regularized electronexchange model potential. We find a narrow S-wave singlet resonance at 5.057 eV of width 0.003 eV in the Ps-Rb system and at 5.067 eV of width 0.003 eV in the Ps-Cs system. Singlet P-...

ABSTRACT A circularly polarized heterodyne light beam is incident on a thin metal film, causing successive reflections and refractions to occur at the two sides of the thin film. The phase difference between pand s-polarizations of the multiple-beam interference signal can be measured accurately with an analyzer and heterodyne interferometry. The phase difference depends on the azimuth angle of...

Structures of pand sd-shell nuclei are studied with the deformed-basis antisymmetrized molecular dynamics method using the Gogny D1S and Skyrme SLy7 forces as effective interactions. By the energy variation with a constraint, energy curves as functions of quadrupole deformation parameter β are obtained. The energy curves for sd-shell nuclei show structure change as a function of β, and suggest ...

We calculate the Schiff moment of the nucleus 199Hg, created by πNN vertices that are odd under parity (P) and time-reversal (T). Our approach, formulated in diagrammatic perturbation theory with important core-polarization diagrams summed to all orders, gives a close approximation to the expectation value of the Schiff operator in the odd-A Hartree-Fock-Bogoliubov ground state generated by a S...

Let Y denote a D-class symmetric association scheme with D ≥ 3, and suppose Y is almostbipartite Pand Q-polynomial. Let x denote a vertex of Y and let T = T (x) denote the corresponding Terwilliger algebra. We prove that any irreducible T -module W is both thin and dual thin in the sense of Terwilliger. We produce two bases for W and describe the action of T on these bases. We prove that the is...
