IR spectroscopic and X-ray studies of variations in the composition of Ni, Cu and (Ni+Cu) ammonium chromates under thermal treatment show that the Ni–Cr system consists of spinel and NiO, and Cu–Cr systems consist of the spinel CuCr2O4 only. In mixed Ni–Cu–Cr systems part of Ni- and Cu-containing components remain independent and part of them form common Ni+Cu phases.

Kinetics and phase transformations are studied for the previously unconsidered decomposition of supersaturated solid solution in magnesium-based alloys Mg–Dy–Sm. The decomposition of solid solution slows when there is an increase in % Dy: % Sm ratio in the alloys. Mg–Sm and Mg–Dy alloys grow harder when Dy and Sm are added to them, respectively. Products of decomposition in ternary Mg–Dy–Sm alloys are the same as in binary alloys Mg–Dy and Mg–Sm but contain combinations of Dy and Sm. 相似文献

Summary The production of nuclear-active and electromagnetic particles, as well as long-lived isotopes in nuclear and electromagnetic
showers generated by cosmic-ray muons at different depths underground is discussed. Characteristics of the secondary components
and their dependence on the depth and the muon energy, obtained in experiments and calculations, are presented. 相似文献

The experimental data obtained on the liquid scintillation detector LSD are analyzed for the purpose of searching for the
solar electron antineutrino flux predicted in the model of spin-flavor precession of the neutrino. The currently most accurate
upper limit on the solar v̄e/v
e
flux ratio is established: Φv̄/Φv⩽1.7% (90% confidence range).

We present schemes for the generation and evaluation of continuous variable entanglement of bright optical beams and give
a brief overview of a variety of optical techniques and quantum communication applications on this basis. A new entanglement-based
quantum interferometry scheme with bright beams is suggested. The performance of the presented schemes is independent of the
relative interference phase which is advantageous for quantum communication applications.

IR spectroscopic and kinetic studies of the interaction between basic carbonates of Cu and Ni and H2CrO4 allows to suppose that catalyst formation is affected by different structures of the initial substances. The formation of mixed Ni–Cu–Cr phases is observed during the step of chromate formation and is preserved after treatment by ammonium.

Amplitude-squeezed pulsed light has been produced using a microstructured silica fibre. By spectrally filtering after the
non-linear propagation in the fibre a squeezing value of -1.7 dB has been measured. A quantum key distribution scheme based
on squeezed light from such microstructured fibres is proposed.

A simple procedure is suggested for estimating changes in the bond lengths q and angles a between them in the excited ππ states
of molecules avoiding calculations of molecular vibrations. The distances q and the angles a are estimated for the triplet
state B1u (ππ*) of the tetm-β-chlomdioxin molecule.
