In the context of the Silberstein theory, by introducing model atoms, the polarizability of pairs of interacting molecules N2-N2, O2-O2, and N2-O2 was studied in relation to the mutual orientation and the intermolecular distance of the molecules in the pairs. The polarizability tensor for the equilibrium configurations of the (N2)2 and (O2)2 dimers was calculated. 相似文献

A comparative study of the longitudinal ρ

resistivities and magnetic susceptibility χ
ac of La0.8Sr0.2MnO3 single crystals and ceramic samples has been conducted in a wide range of temperatures T=1.7–370 K and magnetic fields, H=0–13.6 T. It turned out that the relation ρ

polycrystals, an additional H-dependent contribution to the resistivity tentatively attributed to plane (near grain boundaries) and bulk “defects” of the
magnetic sublattice has been detected. The scattering of carriers by these defects does not make a notable contribution to

due to the critical magnetic scattering calculated in the molecular field approximation reproduces the main features of experimental

A two-dimensional mathematical model has been developed for unsteady thermophysical processes in the industrial duct of an
uranium-graphite reactor with conversion fuel elements of the bush type. The numerical algorithm and computer code have been
developed on the basis of the proposed model to investigate the temperature fields in an aluminum core, fuel, shell as well
as in the cooling water with regard for the design and technological assembly peculiarities. The results of some computational
experiments are presented, which characterize the distribution of temperature fields in the column of fuel elements and in
the cooling water. 相似文献

The radiation-impurity modification of NaF: Eu crystals results in the formation of optically active planar heterostructures with a complex set of luminescence centers, including, in particular, clusters of the Eu2+–Eu3+ type. The luminescence spectra of Eu2+–Eu3+ centers exhibit bands at wavelengths of 409 and 442 nm, which are associated with Eu2+ ions in nonequivalent crystallographic positions, and a band at a wavelength of 610 nm, which is attributed to Eu3+ ions. The luminescence spectra of irradiated NaF: Eu samples contain a broad band with a maximum at 506 nm due to the presence of F2 + F + 3 color centers in the crystal. 相似文献
