    Description / Table of Contents: Im Rahmen der BIXON-ZWANZIG-Theorie wird die Dynamißk von Polymerlösungen unter Berücksichtigung voi hydrodynamischen and excluded-volume-Wechselwirkungen konsistent behandelt. Die Ergebnisse bestätigen die wesentlichsten Eigenschaften des “blob” -Bildes, d. h. den Einfluß der nicht-uniformen Ausdehnung der Kette auf die Relaxationszeiten und die Intrinsic-Viskosität, unterscheiden sich im Detail jedoch von den Ergebnissen von DAUD und JANNINK sowie WEILL und DES CLOIZEAUX. Entgegen den Voraussagen wird ein zweites Plateau in [η(ω)] nicht beobachtet.
    Notes: The dynamics of polymer solutions are consistently treated by the BIXON-ZWANZIG theory including both hydrodynamic and excluded volume interactions. The results confirm generally the essential features of the “blob” picture in polymer dynamics, i.e. the influence of non-uniform chain expansion on the relaxation time spectra and the intrinsic viscosity, but differs in detail from results by DAOUD and JANNINK and WEILL and DES CLOIZEAUX. Especially no second plateau in [η(ω)] is observed.

    Description / Table of Contents: Die Ultraschalldämpfung in einer verdünnten Polymerlösung wird im Rahmen der Kirkwoodschen Diffusionsgleichung untersucht. Eine Frequenzabhängigkeit vom Rouse-Zimm-Typ und eine Relation zwischen Scher- und Volumenviskosität werden erhalten.
    Notes: The ultrasonic attenuation in dilute polymer solutions is treated in the framework of the Kirkwood diffusion equation. A Rouse-Zimm type relaxation behaviour of the ultrasonic attenuation results from the calculations, and a relationship between the intrinsic shear and bulk viscosity is derived.

    Study of the Kα emission spectrum of copper (1986)

    Notes: A simple model of the x-ray Kα emission spectrum of copper metal has been proved to fit the experimental distribution curve of diffracted intensity fairly well, after correcting for profile distortion due to the spectrometer geometry and the diffraction process. Each Kα line can be described by a doublet of overlapping dispersion curves of different height and width. Although the physical relevance of the model is not clear at present, the simple analytical expression of the spectrum may be useful for some problems in x-ray diffractometry.

    Description / Table of Contents: The optimized ROUSE-ZIMM-theory by BIXON and ZWANZIG is used to derive consistently viscoelastic relaxation times of chain models including the hydrodynamic interaction and excluded volume. The intrinsic viscosity is calculated on the basis of these relaxation time spectra.

Die Eigenviskosität wird auf der Grundlage der Relaxationszeit-spektren berechnet.

    Electrodes for REMPI spectroscopy in static gases and calculation of REMPI intensities: Application to molecular oxygen (1994)

    Notes: Resonance-enhanced multiphoton ionization (REMPI) of 16O2X3∑g - (ν = 0) through (3sσg)d 1Πg, (ν = 0) by using (2 + 1) one-colour photons is reported. This REMPI process, already observed and analysed by other authors at low pressure and low rotational temperature with mass spectrometry detection, is used to test our first detector of ionizations. Experimental difficulties have led to the design of an original arrangement of electrodes to collect electrons at room temperature and 1 Torr pressure of static molecular oxygen. A calculated spectrum is compared with the observed REMPI spectrum. The calculation uses the polarizability tensor and takes into account the competition between ionization and predissociation of the Rydberg state.

    Notes: Characteristics of gel permeation chromatograms are investigated for three molecular distribution functions assuming a linear relation between elution volume and the logarithm of solute molecular weight. The average molecular weight, Mgpc, determined by the peak position of a chromatogram lies between the Mw and Mn for a polydisperse polymer.
