    The foundations of relativity (1981)

    Notes: Abstract In a previous paper a stochastic foundation was proposed for microphysics: the nonrelativistic and relativistic domains were shown to be connected with two different approximations of diffusion theory; the relativistic features (Lorentz contraction for the coordinate standard deviation, covariant diffusion equation) were not derived from the relativistic formalism introduced at the start, but emerged from diffusion theory itself. In the present paper these results are given a new presentation, which aims at elucidating not the foundations of quantum mechanics, but those of relativity. This leads to a discussion of points still controversial in the interpretation of relativity. In particular two problems appear in a new light: the character of time and length alterations, and the privileged role of the velocityc. Besides, the question of a possible limitation of relativity (and more generally of the laws of mechanics) in the domain of particle substructure is raised and supported by exemples drawn from the hydrodynamical model of a spinned particle. Suggestions are presented for the possibility of a deeper conceptual unification of special and general relativity.

    Stochastic foundation for microphysics. A critical analysis (1981)
    Springer
    Foundations of physics 11 (1981), S. 699-720

    Notes: Abstract The stochastic scheme proposed in a previous paper as subjacent to quantum mechanics is analyzed in the light of the difficulties and criticisms encountered by similar attempts. It is shown that the limitation of the domain where the theory is valid gives a reply to the criticisms, but restricts its practical usefulness to the description of basic features. A stochastic approach of the hadron mass spectrum, allowing the scheme to emerge in the domain of experimental verification (to be worked out in a later paper) is outlined. The model is found not to be in disagreement with Bell's argument opposed to hidden variables; a same origin is suggested for the difficulties encountered in both domains. The views proposed are compared with the Copenhagen interpretation: common points and divergences are analyzed.

    A model for the Schrödinger zitterbewegung and the plane monochromatic wave (1981)
    Springer
    Foundations of physics 11 (1981), S. 863-872 
    Details
    ISSN: 1572-9516

    Topics: Physics
    Notes: Abstract The stochastic approach worked out in earlier papers is applied to the Dirac fluid. It gives a model of the Schrödinger zitterbewegung, from which, by the spinor-vector correspondence, a model of the plane monochromatic wave in the rest frame is derived. The relation of the scheme with quantization is found to have the same character as in the previous papers. The link of spin with relativity is explained.

    Comparison of indium-111 oxinate labelled autologous granulocytes with indium-111 oxinate and indium-111 chloride as abscess scanning agents (1980)
    Springer
    European journal of nuclear medicine 5 (1980), S. 63-68

    Notes: Abstract Bacterial abscesses were evoked in goats. Imaging of these abscesses was obtained by means of labelling autologous granulocytes with 111In oxinate, reinjection of the cells into the animal, and scintigraphy by gamma camera one day later. Comparable imaging results, however, were obtained after intravenous injection of 111In oxinate or of 111In chloride. The gamma camera images were supported by tissue distribution studies. In the case of administration of 111In oxinate to the goats, the radioactivity accumulated in the cell fraction of the blood to a significant extent. This did not occur in the case of plain 111In chloride. It remained unexplained why such different accumulation in cells did not result in differences in the scintigraphic studies. Blood clearance studies supplied conclusive evidence that the granulocytes stayed in the circulation for several days following labelling with 111In oxinate and reinjection of the cells into the animals.

    Molecular vibrational constants of some simple polyatomic molecules. Methyl, silyl, and germyl halides (1984)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The force constants and compliance constants of methyl, silyl, and germyl fluoride, chloride, bromide, and iodide have been calculated by the iterative consistency method. Using the force fields so obtained, centrifugal distortion constants, Coriolis coupling constants, and mean amplitudes of vibration have been computed and compared with experimental data, where available.
