The temperature dependence of the 109Ag γ-ray self-absorption was investigated for the horizontal and vertical directions of emission. The source was a single-crystal
silver plate containing atoms of parent radionuclide 109Cd. Gamma-radiation of this γ-source and that of the monitoring γ-source, 57Co, were registered by a pair of Ge(Li)-detectors. As a result of cooling the source from 77 K to ~12 K a relative decrease
was observed of the intensity of the horizontally emitted γ-rays equal to 0.00064±0.00044. For the vertical direction the
corresponding intensity change turned out to be -0.00047±0.00051. Although these data, as one would see, give some evidence
for the possible effect of the gravitation on the resonant γ-ray absorption, future measurements must show if these results
aren’t a consequence of any apparatus effect. The ways for developments in this study are discussed and some hindrances are
considered.

Backscattering of high-power laser pulses in a randomly inhomogeneous media containing microparticles suspended in a liquid is treated theoretically. Relationships for the temporal correlation function of multiply scattered radiation, which account for acceleration of particles in the field of optical radiation, sure derived for the first time. A new method for determination of particle velocities based on correlation properties of scattered light is proposed. 相似文献

Data from BEBC experiments are combined to provide large statistics for neutrino interactions. ChargedD
* mesons are produced in (1.22±0.25)% of neutrino and (1.01±0.31)% of antineutrino charged current interactions. The mean fraction of the hadronic laboratory energy taken by theD
*+ in these events is 0.59±0.03±0.08. Less than 18% of all chargedD
* mesons from (anti)neutrino interactions are found to be daughters ofD

All six exclusive single pion production processes from neutrino and antineutrino charged current interactions are studied in the energy range between 3 and 30 GeV. Using a quark model for single pion production from Rein and Sehgal we fitted the aximal mass parameter from total cross sections and compare the results with values from other experiments and the world-averages. 相似文献

A study of a number of chiral cisoid cyclic enamino ketones by the circular dichroism method showed that they contain an inner disymmetric chromophore. The presence of homoconjugation of the phenyl and enamino ketone chromophores as a result of the drawing together of their orbitals in space was also established.Communication XXXVI from the series Stereochemical Studies; see [1] for communication XXXVTranslated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 511–515, April, 1976. 相似文献

The production of μe-pairs is studied in interactions of neutrinos with nuclei of heavy freon in the SKAT bubble chamber experiment. A rate of μ? e + to charged current interactions above the charm threshold of \(R^{\mu ^ - e^ + } = (4.6 \pm 1.2) \cdot 10^{ - 3} \) is found. The properties of the observed μ? e + events can be well described by assuming them to originate from the semileptonic decay of quasielastic produced charmed baryonsΛ c and inclusive charmedD-meson production. The rates for these reactions are found to be (6.7±3.5)×10?2 and (2.5±0.9)×10?2, respectively. A total charmed particle production rate of (9.2±3.6)×10?2 is calculated. 相似文献

Low-frequency dielectric losses (tanδ) in barium titanate ceramics with crystallite sizes of ~100 nm near the Curie temperature are studied. It is shown that the observed tanδ maximum is described by a low-frequency fluctuation mechanism of dielectric losses. An analysis of experimental data shows that the critical nucleus size in ultrafine material is smaller than the one in bulk barium titanate. 相似文献
