Limit theorems for twists of <Emphasis Type="Italic">L</Emphasis>-functions of elliptic curves

We obtain a limit theorem for L-functions of elliptic curves twisted by Dirichlet characters with increasing modulus.     

Density of indium antimonide at high temperatures

The density of solid and liquid indium antimonide was studied by irradiating the samples with a narrow beam of monochromatic gamma-radiation in the temperature range of 293–1950 K, including the range of melting — crystallization. The measurement errors for the density and thermal expansion coefficients were ±(0.25–0.40) % and ± 4 %, correspondingly. The approximating equations and tables of reference data were obtained for the temperature dependence of thermal properties. Measurement results were compared with the known published data. The work was financially supported by the Russian Foundation for Basic Research (Grant No. 06-08-00040).

Experimental Investigation of the Enthalpy and Heat Capacity of Liquid Cesium

The enthalpy of liquid cesium in the temperature range from 431 to 976 K was measured by a drop method on an isothermal calorimeter. The approximation equation of enthalpy was obtained and the isobaric heat capacity was determined. The estimated errors in the enthalpy and heat capacity data are 0.5% and 1.5%, respectively. The obtained results are compared with the literature data. The position of the minimum heat capacity of liquid cesium was clarified (733 K). Tables of recommended values of caloric properties in the investigated temperature range were developed.     

Measurement of angular distributions of Drell-Yan dimuons in p+d interactions at 800 GeV/c

We report a measurement of the angular distributions of Drell-Yan dimuons produced using an 800 GeV/c proton beam on a deuterium target. The muon angular distributions in the dilepton rest frame have been measured over the kinematic range 4.5相似文献   

Thermal expansion of artificial graphites in the temperature range 293–1650 K

The article presents the results of studying the thermal expansion of MPG-6 and AXF-5Q graphites and graphite composite based on ¹³C isotope in the temperature range 293–1650 K. Measurements were performed with dilatometric method in DIL-402C unit manufactured by NETZSCH (Germany), with the accuracy of (1÷4)×10^?7 K^?1. Approximation dependences of average integral coefficient of linear expansion on temperature have been obtained and reference tables calculated. It is shown that the coefficient of thermal expansion of ¹³C composite is much lesser than for MPG-6 and AXF-5Q. The explanation of this phenomenon is provided in the paper.     

Interdiffusion in potassium-lead melts in a wide range of concentrations

Interdiffusion in potassium-lead melts containing 30, 40, 50, 66.7, and 84.4 at. % Pb was investigated using gamma-ray attenuation technique in the temperature range from 550 to 970 K. It was found that the concentration dependence of interdiffusion coefficient has a maximum in the vicinity of 40–50 at. % Pb. It was shown that this feature is associated with the trend of forming ionic complexes of K₄Pb₄ in liquid alloys.
