Experiment for Testing Special Relativity Theory
An experiment aimed at testing special relativity via a comparison of the
velocity of a non matter particle (annihilation photon) with the velocity of
the matter particle (Compton electron) produced by the second annihilation
photon from the decay Na-22(beta^+)Ne-22 is proposed.Comment: 7 pages, 1 figure, Report on the Conference of Nuclear Physics

Strong fragmentation of low-energy electromagnetic excitation strength in Sn
Results of nuclear resonance fluorescence experiments on Sn are
reported. More than 50 transitions with MeV were
detected indicating a strong fragmentation of the electromagnetic excitation
strength. For the first time microscopic calculations making use of a complete
configuration space for low-lying states are performed in heavy odd-mass
spherical nuclei. The theoretical predictions are in good agreement with the
data. It is concluded that although the E1 transitions are the strongest ones
also M1 and E2 decays contribute substantially to the observed spectra. In
contrast to the neighboring even Sn, in Sn the
component of the two-phonon quintuplet built on top of
the 1/2 ground state is proved to be strongly fragmented.Comment: 4 pages, 3 figure
Search for the electric dipole excitations to the multiplet in Sn
The odd-mass Sn nucleus was investigated in nuclear resonance
fluorescence experiments up to an endpoint energy of the incident photon
spectrum of 4.1 MeV at the bremsstrahlung facility of the Stuttgart University.
More than 50 mainly hitherto unknown levels were found. From the measurement of
the scattering cross sections model independent absolute electric dipole
excitation strengths were extracted. The measured angular distributions
suggested the spins of 11 excited levels. Quasi-particle phonon model
calculations including a complete configuration space were performed for the
first time for a heavy odd-mass spherical nucleus. These calculations give a
clear insight in the fragmentation and distribution of the , , and
excitation strength in the low energy region. It is proven that the
component of the two-phonon quintuplet built on
top of the ground state is strongly fragmented. The theoretical
calculations are consistent with the experimental data.Comment: 10 pages, 5 figure

An experimental prototype of electric motor on permanent (FeNdB) magnets with switchable magnetic flux with two sectioned stators and a rotor using SMC material based on encapsulated metal powders has been developed. The method of manufacture of magnetic cores by powder metallurgy method on the basis of magnetically soft encapsulated titanium dioxide composites has been developed, including computer modeling of magnetic cores components, creation of tooling for their manufacture by pressing and selection of technological modes of pressing. Press set for manufacturing stator components by pressing in the form of a mold was made of hardened 5XHB steel. With its use magnetic components for twostator combined electric motor are pressed. The main electromagnetic characteristics of the components were measured with an express magnetometer. Complex studies showed that the magnetic components have sufficient strength and the necessary electromagnetic characteristics to create a two-stator combined electric motor of this type. An experimental sample of electric motor with maximum power of 15 kW was created on the basis of manufactured magnetic components. Advantages of composite material over electrical steel and other soft magnetic alloys allow providing their wider application in electric machines in order to increase specific power at high speed of rotation with less losses.Π Π°Π·ΡΠ°Π±ΠΎΡΠ°Π½ ΡΠΊΡΠΏΠ΅ΡΠΈΠΌΠ΅Π½ΡΠ°Π»ΡΠ½ΡΠΉ ΠΎΠ±ΡΠ°Π·Π΅Ρ ΡΠ»Π΅ΠΊΡΡΠΎΠ΄Π²ΠΈΠ³Π°ΡΠ΅Π»Ρ Ρ ΠΏΠ΅ΡΠ΅ΠΊΠ»ΡΡΠ°Π΅ΠΌΡΠΌ ΠΌΠ°Π³Π½ΠΈΡΠ½ΡΠΌ ΠΏΠΎΡΠΎΠΊΠΎΠΌ Ρ Π΄Π²ΡΠΌΡ ΡΠ΅ΠΊΡΠΈΠΎΠ½ΠΈΡΠΎΠ²Π°Π½Π½ΡΠΌΠΈ ΡΡΠ°ΡΠΎΡΠ°ΠΌΠΈ ΠΈ ΡΠΎΡΠΎΡΠΎΠΌ Π½Π° ΠΏΠΎΡΡΠΎΡΠ½Π½ΡΡ

Increase of saturation current in unipolar field-effect transistor due to bulk electric conductance of organic semiconductor
We considered an organic field-effect transistor (OFET) based on a squaraine (SQ) fiber, where the electric conductance of the accumulation channel is comparable with the bulk conductance of the SQ fiber. Each of the measured output and transfer current-voltage characteristics was decomposed into two components, representing the conductance of the accumulation channel and the bulk. We present in detail, how the bulk conductance of the fiber can transform the output characteristics of the unipolar OFET. For positive drain and gate voltage, the hole injection from the drain always takes place when a drain voltage is applied. Depending on the ratio between the electron density (ns) injected from the source into accumulation channel and the hole density (pb) injected from the drain into the bulk, the saturation current of the unipolar OFET is constant (pb < ns) or exhibits increase (pb β₯ ns)
When hole extraction determines charge transfer across metal-organic-metal structure
We examined the charge transfer in metal-organic-metal structure, where the contact resistance of the extracting interface is larger than the resistance of the organic crystalline material and the resistance of the injecting interface. If direct tunneling (low voltage) and Fowler-Nordheim tunnelling (high voltage) across both interfaces take place, part of the injected holes remains located in the organic crystal because of the blocking action of the extracting interface, but not because of traps within the organic crystalline material (which was negligible). If Fowler-Nordheim tunneling across the injecting interface and direct tunneling across the extracting interface take place for high voltages, the latter leads to the deviation of the total current-voltage characteristic from the power law with to Ohm's law with
