    Notes: Spectrally shifted Raman light with time was observed from two-layered spherical targets irradiated with 527 nm random phased laser light. The target was composed of a foam shell and an outer thin plastic layer. The Raman spectrum shifted rapidly to the short-wavelength side during the laser pulse. The start timing was earlier than that of the usually observed Raman light at an experiment with a single-layered plastic shell target. It was inferred that a plasma shoulder with a long scale length moved outward on the expanding plasma, consistent with the observed Raman light. © 1995 American Institute of Physics.

    Notes: The performance data of an undulator soft x-ray beamline based on the cylindrical element monochromator concept are described. Photon fluxes over 1012 photon/s 0.1% b.w. are achieved with the slit width of 100 μm at the harmonic peaks of a 13-period undulator. The maximum resolution obtained at the N K edge (E/ΔE) is ≈5000 with the slit width of 10 μm. The beamline is equipped with a multipurpose analytical instrument having a hemispherical electron analyzer and other detectors. The system is used for both x-ray photoelectron spectroscopy and x-ray absorption fine structure analyses for surface and materials science. © 1995 American Institute of Physics.

    Optical and electrical properties of Ag-As-S glasses (1995)

    Notes: Physical properties of Ag2S-As2S3 glassy alloys have been studied as a function of the Ag atomic concentration x. With an increase in x, the optical-absorption edge exhibits a red shift, while the steepness of the Urbach tail changes little. In the glasses with x≥15, the electrical conductivity is governed by Ag+ ionic conduction. The ionic conductivity exponentially increases with x, and in contrast the hole conductivity hardly changes with x; however, the activation energies for the ionic and the hole conductivity are nearly the same at about 0.4 eV for compositions with 15 ≤x≤35. These observations are discussed on the basis of atomic and electronic structures in Ag2S-As2S3 glasses. © 1995 American Institute of Physics.

    Notes: A series of optical transitions between higher conduction subbands and higher heavy-hole subbands have been observed between 77 K and room temperature in photocurrent spectra of p-i-n photodiodes including 5-nm-wide InGaAs/InAlAs multi-quantum wells. The quadratic dependence of the transition energy on the heavy-hole quantum number, l=1,2 and 3, has been clarified for each conduction-electron quantum number, n=1 and 2. This experiment evidences the applicability of a particle-in-a-box model to the energy level determination. The carrier effective masses in InGaAs wells and the related band discontinuities were analyzed. © 1995 American Institute of Physics.

    Photoelectric properties of Ag–As–S glasses (1995)

    Notes: Photoconductive and photovoltaic responses in glassy Ag–As–S ion-conducting semiconductors have been studied. The ac conductivity of the glass increases with illumination, while the increase is ascribed to enhanced ionic conduction caused by temperature rise and to interfacial photoeffects. Bulk photocurrent is not detected. By contrast, photovoltages appear in Ag–As–S samples having sandwich and floating electrodes. The photovoltaic characteristics are discussed in terms of classical electrodynamics assuming interaction between electronic carriers and Ag+ ions. © 1995 American Institute of Physics.

    Notes: We present the crystal-orientation dependence of the magnetic circular dichroism (MCD) spectra of ferromagnetic (11¯01) and (0001) MnSb epitaxial films grown by molecular beam epitaxy on (001) GaAs and (0001) sapphire substrates, respectively, where very large anisotropy is clearly observed at around 3.0 and 4.7 eV. The anisotropy of the MCD spectra is discussed in connection with the magnetocrystalline anisotropy. © 1995 American Institute of Physics.

    Numerical Liouville approach: Formulation of third-order nonlinear optical susceptibilities (1995)

    Notes: As a continuation of a previous paper [Phys. Rev. A 50, 2989 (1994)], this article develops and describes in detail the new nonperturbative approach to the third-order nonlinear optical susceptibilities χ(3)g(ω) in third-harmonic generation (THG), electric-field-induced second-harmonic generation (EFISH), degenerate four-wave mixing (DFWM), electric-field-induced optical rectification (EFIOR), and electric-field-induced Kerr effect (EFIKE) for N-state quantum systems interacting with intense electric fields. The present method utilizes the Fourier transformation of numerically exact solutions of the Liouville equation, so that it can provide both real and imaginary nonlinear optical spectra valid for arbitrary laser intensities, frequencies, and relaxation. As an application of the method, we investigate the characteristics of nonlinear optical spectra in THG, EFISH, and DFWM for a three-state model that mimics the electronic excited states of t-octatetraene obtained from a full configuration interaction (FCI) calculation using the Pariser–Parr–Pople (PPP) Hamiltonian. Comparisons between the present nonperturbative and the conventional perturbative results are also carried out. The magnitudes of the third-order nonlinear susceptibilities in the off-resonant region show the following trend: χ(3)(THG)(approximately-greater-than)χ(3)(EFISH)(approximately-greater-than)χ(3)(DFWM), with χ(3)(THG) exhibiting the largest frequency dispersion. © 1995 American Institute of Physics.

    Numerical Liouville approach: Three-type analysis of virtual excitation processes of third-order nonlinear optical spectra in third-harmonic generation (1995)

    Notes: An analysis method based on virtual excitation processes is developed in numerical Liouville approach, which is a new nonperturbative method presented before. In this analysis method (NLA three-type analysis method), third-order nonlinear optical susceptibilities χ(3)g(ω) obtained by the NLA method can be divided into the three-type virtual excitation processes similar to the three-type analysis based on the time-dependent perturbation theory (TDPT three-type analysis). The NLA three-type analysis method is superior to the TDPT three-type analysis one in the points as follows: (1) the NLA three-type analysis can treat the phenomena caused by the intensity-dependent nonlinear susceptibilities including nonperturbative effects and (2) the NLA three-type analysis can divide the resonant nonlinear susceptibilities into three types of virtual excitation processes. In order to explain the procedure of the present analysis, we try to elucidate the characteristics of virtual excitation processes of nonlinear optical spectra in THG for a three-state model that mimics the electronic excited states of a system with noncentrosymmetric charge distribution. © 1995 American Institute of Physics.

    Characterization of IgE-binding epitopes on Candida albicans enolase (1995)

    Notes: Candida albicans enolase is one of the important allergens in Candida allergy. We isolated and purified 46 kDa C. albicans enolase (CAE) from C. albicans and characterized epitopes for IgE antibody by lectin-blotting and enzymatic digestion followed by sodium dodecyl sulfale polyacrylamide gel electrophoresis (SDS-PAGE) and immunobiotting. Lectin blotting and deglycozilation indicated that this protein did not contain polysaccharide side chains. The purified CAE and recombinant fusion protein produced from CAE gene possessed common epitopes for IgE antibody. We estimated IgE binding epitopes on the basis of reported amino acid sequences from the analysis of cDNA encoding CAE. V8 protease digestion of CAE gave six polypeptide fragments (A-F). The N-termini of each fragment were confirmed by amino acid sequence and the C-termini were estimated by molecular weights of each fragment and the specific cutting site of V8 protease. Fragment C (25.0 kDa; F-171-I-399) reacted to 90% IgE antibodies examined, whereas fragments D (21.0 kDa; F-171-1-360), E (16.2kDa: F-171-D-317) and F (13.0kDa; A-47-E-170) showed no IgE binding. Our results suggest that epitopes for IgE antibodies exist near the C-terminal of the protein.
