AbstractAbstract
[en] The problem of interaction of radiation having arbitrary polarization and intensity with 1/2-1/2 and 1-0 resonant systems was solved. Exact expressions for the vectors of orientation of lower and upper states of the 1/2-1/2 system and for the vector of orientation and tensor of alignment of the 1-0 system in the field of elliptically polarized radiation are obtained. The influence of disorientating atomic collisions on the process of optical pumping was also studied. 10 refs

AbstractAbstract
[en] The X-ray transition radiation and Cherenkov radiation in an inverse medium are investigated. The spectral distribution of energy as well as the full energy and photon number of these radiations are obtained. It is shown that the Cherenkov radiation can be used to create the new counters for identification of elementary particles with very high energies. This radiation can serve also as an intensive source of hard photons. 4 refs

AbstractAbstract
[en] An analysis of quantum fluctuations of light for the process of intracavity two-photon absorption from two coherent modes of radiation field with different frequencies in a non saturating absorber is presented. Effects of squeezing of quantum fluctuations intensities of two anticorrelated modes at the cavity output below the corresponding vacuum and coherent levels of fluctuations are found. 27 refs

AbstractAbstract
[en] In the positive P-representation the joint fluctuations of photon numbers and phases were investigated numerically for intracavity third harmonic generation. The third harmonic at the right from the bifurcation point of the optical system is most probably to register at two states with the same probabilities (superposition state). The oscillation time of the system between these states has the same order of magnitude with the photon lifetime in cavity. In the joint distribution function of fundamental mode phases and third harmonic there is a dip, which size increases with removing of the system to the right from the bifurcation point. 9 refs

AbstractAbstract
[en] In samples with the Cu1-x-yBixPbySr2CaCu2Oz composition obtained by solid state synthesis method a superconducting phase with a critical temperature Tc∼85K is discovered. Superconductivity is observed in the samples rapidly cooled down from synthesis temperatures. It is supposed that superconductivity is caused by the presence of the (Bi,Pb)Sr2CaCu2O2 compound. 7 refs
