Anisotropy of the faraday rotation in orthoferrites

Faraday rotation in plates of orthoferrites, cut normally to the optical axis, depends strongly on the polarization of the incident light in the vicinity of the absorption bands, where linear dichroism is large     

Investigation of the structure and physicomechanical properties of polypropylene film

The authors have investigated the effect of the dynamic degree of crystallinity, stereoisomeric composition, intrinsic viscosity, and other factors on the nature of the structure formed when polypropylene is made into film and on the physicomechanical properties of the film.Mekhanika Polimerov, Vol. 3, No. 6, pp. 970–976, 1967

Effect of the composition and structure of the surface layer on the functional properties of a core(Al2O3)-Shell(VO x /TiO y ) composite

Molecular layering method was used to synthesize vanadium, titanium, and vanadium-titanium oxide structures of various compositions and structures on the surface of γ-Al₂O₃. The systems obtained and the starting aluminum oxide were identified by chemical-analytical and adsorption methods, X-ray diffraction analysis, and X-ray photoelectron spectroscopy. The catalytic properties of the products obtained were examined for the example of oxidative dehydrogenation of methanol. It is shown that the reactivity of the samples is affected not only by the concentration of catalytically active vanadium oxide structures, but also by their remoteness from the surface of the starting matrix, controlled by the thickness of the titanium oxide sublayer.     

InclusiveK s 0 , Λ and\bar \Lambda-production in\bar p p-interactions at 22.4 GeV/c

InclusiveK _s ⁰ , Λ and \(\bar \Lambda\) -production has been investigated in \(\bar p\) p-interactions at 22.4 GeV/c. Total and topological cross sections and multiplicity characteristics of neutral strange particles have been determined. DifferentialK _s ⁰ and Λ-cross sections and also characteristics of annihilation processes with neutral kaon production have been studied. It is shown that the difference of the shapes of the invariantx-distributions forK-mesons in the fragmentation region for annihilation and non-annihilation processes can be described in the framework of the “dual” valon model, but not by considering the current (undressed) quark recombination mechanisms only. The polarization of Λ and \(\bar \Lambda\) -hyperons has been measured.     

Anomalous density effect near the interface between two media

A theoretical investigation is presented for the local energy loss of a relativistic charged particle and theK-shell excitation cross section σ _K when the particle crosses a sharp interface between two different media. The logarithmic increase of the local energy loss andσ _K with the particle energy is shown to differ essentially from the case of a homogeneous medium. The calculations ofσ _K for aluminum and copper foils are in good agreement with the experimental data.
