    Abstract This work is a continuation of the experimental and theoretical investigations of the effect of the Z 1 3 correction to the stopping power of ions on the passage of heavy ions 40Ar, 56Fe, 197Au, 131Xe, and 238U with energies of about 1 GeV/nucleon through a homogeneous medium. The previously observed systematic deviations of the calculations based on the first Born approximation to the scattering of a particle by the atomic electrons in the medium from the experimental values of the total ionization ranges of the nuclei and their stopping powers is confirmed. The discrepancy increases with the atomic number of the projectile nucleus. It is shown that the Z 1 3 correction in the form proposed by Jackson and McCarthy eliminates, especially for ions with Z 1〉50, the systematic discrepancy between the computed and experimental values. For the experimental energy range relativistic Mott scattering of a particle by the atomic electrons in the target makes the dominant contribution to the observed Z 1 3 effect.

    Notes:
    To identify the allergenic components of honey we studied 22 patients with a history of systemic allergic symptoms following honey ingestion. The group of honey-allergic patients was compared with three control groups: 10 subjects sensitized to artemisia, 10 with honey bee venom allergy and 10 without a history of atopy or bee sting reactions. The allergological tests included skin tests and RAST with three different kinds of Swiss honey (dandelion, forest and rape), pollen of compositae species, celery tuber, extract of bee pharyngeal glands, honey bee venom and bee whole body extract. The results show that 3/4 of honey-allergies are sensitive to dandelion honey and 13 of 22 also to compositae pollen. Nine of the honey allergic patients were sensitized to honey bee venom, 3 also to bee pharyngeal glands and to bee whole body extract. Analysis of diagnostic tests and RAST inhibition studies suggest that besides compositae pollen other allergens, most likely of bee origin are important. In honey allergies primary sensitization may be due either to the honey itself, to airborne compositae pollen or even to cross-reacting bee venom components.

    Notes:
    Abstract An acoustical method is proposed for the determination of the elastic and piezoelectric constants of crystals of classes 6mm and 4mm. The method is based on the technique developed for orthorhombic crystals of class mm2 and described in the previous paper [9]. Only three samples are required for the determination of all elastic and piezoelectric constants of crystals belonging to the two symmetry classes of interest; for the crystals of class 6mm, only two samples are necessary. The proposed method can be used only when the signs of the piezoelectric constants are known beforehand. Knowing the sign of electrostriction for the crystals under study, the relative signs of the piezoelectric constants can be uniquely determined in accordance with the data reported earlier [10]. This approach allows one to extend the method used in the previous paper [9] to crystals of classes 6mm and 4mm.

    Notes:
    Basic conclusions 1. The selection criteria of central nuclear collisions were investigated, and the field of their applicability was given. The impact parameters of two nuclei for selected events are found to be ≲ 3 fm. 2. Events classified as central collision ones are accompanied by the emission of at least one g-particle emitted backward in the laboratory coordinate system. 3. Both the multiplicity of relativistic (s) particles and the number of pions among them are proportional to the mass of projectile nucleus. 4. The sharp increase in s-particle forward collimation with increasing projectile nucleus mass is related to the increase in inelastically scattered protons of this nucleus. 5. The calculations by the cascade-evaporation model for4He(Ag, Br) collisions answer a qualitative character of experimental data behaviour but overestimate the degree of target nucleus desintegration.

    Notes:
    Abstract The possibilities of current-sheet formation in two-dimensional magnetic fields with a null line as well as the characteristic features of the plasma dynamics under high initial pressure conditions (helium, P 0≈300 mtorr) are investigated for the first time. It is shown that current-sheet formation and efficient compression of the plasma into a sheet require that the magnetic field gradient be sufficiently large. A brightly emitting compact region with electron density N e∼9×1016 cm−3, an order of magnitude higher than the gas atom density, was observed to form at the center of the layer.

    Notes:
    Abstract Computer calculations are made of the intensity of multiple small-angle neutron scattering using the general Moliére formula [8] over a wide range of variation of the Born parameter, embracing the diffraction and refraction regimes, and a transition region between diffraction and reflection. A comparison is made with approximate formulas obtained earlier by Maleev et al. [9, 10] in the limiting cases of the Born parameter α ≪ 1 and α ≫ 1 for the diffraction and refraction regimes, respectively. It is shown that over a wide range of values of α the results of the calculations using the approximate and general formulas are the same. The theoretical conclusions were checked experimentally using data from measurements of small-angle neutron scattering for the domain structure of ferromagnets. Measurements were made of the neutron beam broadening for samples of different thickness and these were used to determine the effective domain sizes in pure iron and nickel exposed to thermal treatment and plastic deformation, and also in the Invar alloys Fe65Ni35and Fe3Pt. An analysis is made of the angular dependence of magnetic small-angle neutron scattering at the asymptote.

    Notes:
    Abstract The possibility of the formation of current sheets in 3D magnetic configurations with singular X-lines was studied experimentally. It is shown that a sheet can be formed in the presence of the longitudinal magnetic-field component directed along the X-line, in which case the longitudinal component can exceed the transverse component everywhere inside the plasma. Characteristic of the CS formation in 3D magnetic configurations with X-lines are an increase in the longitudinal magnetic-field component inside the sheet and a decrease in the plasma compression ratio as compared to 2D configurations with null-lines. If the longitudinal component exceeds a certain critical value, a sheet cannot be formed: instead of a sheet, there appear two sheaths separated by a cavity with a local minimum in the electron density.

    Abstract Adsorption of polynuclear palladium(ii) hydroxocomplexes (PHC) by carbon materials (CM) was studied. It was found that PHC are adsorbed from aqueous solutions without a change in their chemical composition and are composed of clusters (〈10 A) with metalmetal distances typical of the PdO chain structure. Three-dimensional ordered particles with the PdO structure were formed upon adsorption of PlIC on carbon materials at room temperature or after the PHC suspension was dried in air at 400 °C (the size of the particles was 15 and 25 A, respectively). Calculation of the electron-microscopic images of the adsorbed PHC with atomic resolution based on crystal structure modeling showed that PdO particles containing -100 palladium atoms is the final product after drying of the adsorbed PHC.

    Conclusions 1. The matrix IR spectra of 2,3-dimethyl- and 2,3,7,8-tetramethyl-5-germaspiro [4.4]-nona-2,7-dienes in argon at 12 K are reported for the first time. 2. The possibility of the formation of the corresponding germylene, namely, 3, 4-di-methylcyclopentene-3-germylene in the thermal decomposition of 2,3,7,8-tetramethyl-5-germa-spiro [4.4] non-2,7-diene was demonstrated by chemical capture and matrix IR spectroscopy. This germylene undergoes complete decomposition under the vacuum pyrolysis conditions to metallic germanium and 2,3-dimethyl-1,3-butadiene.
