    Notes: Abstract— Rabbits were immunized with chromomembrin B, i.e. a membrane protein isolated from chromaffin granules of bovine adrenal medulla. When the rabbit sera were tested by immunodiffusion in the presence of various detergents, only negative results were obtained, whereas with complement fixation antibodies could be demonstrated. With this method the subcellular distribution of chromomembrin B in bovine adrenal medulla was determined. The results demonstrate that this protein is specifically localized in the membranes of chromaffin granules. In the mitochondrial and microsomal fractions it is present only in small amounts which are attributable to a contamination of these fractions with chromaffin granules. The subcellular distribution of chromomembrin R in bovine splenic nerves indicates that this antigen is also found in the membranes of noradrenalinestoring vesicles of sympathetic nerve. Chromomembrin B or a related antigen was detected in chromaffin grades isolated from pig and rat adrenal and in those isolated from a human phaeochromocytoma. It is also present in total membranes obtained from posterior and anterior hypophysis, but it is absent from membranes isolated from parotid gland, liver and adrenal cortex. This paper illustrates how a membrane protein which requires detergents for its solubilization can be characterized and measured by immunological methods.

    γγ-angular correlations perturbed by stochastic fluctuating fields (1973)

    Notes: Abstract On the base of the stochastic model of M. Blume for time-dependent hyperfine interactions the perturbation factors of the angular correlation function are evaluated. The results of numerical calculations for some special configurations of stochastic fluctuating field gradients as well as magnetic fields are presented. In the medium range where the fluctuation rates are comparable with the nuclear precession frequencies, interesting features are worked out for the spinrotation spectra. For the limiting case of very fast fluctuations it is proved that the well-known exponential decay of anisotropy as predicted by the theory of Abragam and Pound appears.

    Time-dependent electric quadrupole interactions in (NH4)3HfF7 (1973)
    Springer

    Notes: Abstract Spinrotation spectra of polycrystalline (NH4)3HfF7 in which radioactive181Hf was incorporated have been measured in the temperature range from −196 °C to + 70 °C. The spectra were interpretated on the base of the stochastic model of M. Blume. It was assumed that reorientations of the [HfF7]3− polyhedra take place at random. The resulting fluctuation rates can be understood as to be caused by an activation process. The activation energy was determined to 0.324(12) eV in agreement with NMR measurements on19F in this compound.

    Field desorption mass spectrometry with indirect heating of the emitter (1973)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 7 (1973), S. 1007-1009

    Notes: In field desorption mass spectrometry it is in many cases more expedient to heat the field anode indirectly by i.r.-radiation instead of the usual method of electric heating to achieve higher relative molecular ion intensities.
