[en] The interaction potential between two electpons in the field of a circularly polarized light wave of arbitrary intensity is studied. At large distances the interaction potential possesses local minima at which coupled states may form in a sufficiently strong field. In the near zone the potential in a strong field is of a noncoulomb form. The contribution of coherent effects to the light pressure on the two electrons is derived

[en] The anomalous correlator of the complex amplitudes of a scattered field is calculated. It differs from zero in a running wave for forward scattering, and in a standing wave for oppositely directed scattered rays. The anomalous correlator can be used in measuring the width of atomic resonances on the background of strong Doppler broadening in a linear approximation according to the intensity of the external field.

[en] Using ESR spectroscopy the authors investigated the photolysis and radical composition of a plastic lubricant composed of polyethylene, perfluoroalkylpolyester 240, oleic acid, mineral oil, and benzophenone. The spectra are comprehensively analyzed. Hyperfine structure and spin trapping are given for the polyalkyl radicals. The photochemical modification of the lubricant leading to these radicals, and their reaction with oxygen, are determined to be responsible for the enhanced adhesion of the plasticizers to the polymer

[en] The upper limits of the cross sections for productions of superdense nuclei are determined on the level of 5x10^-33-10^-28 cm² at irradiating ₂₈Ni⁵⁸, ₈₂Pb²⁰⁸, ₂₉Cu⁶³, ₇₃Ta¹⁸¹, targets with ₆C¹² protons with 1.90; 3.36; 9.80 GeV/c momenta; with α particles of 0.95 GeV/c nucleon momentum, with carbon nuclei of 3.36 GeV/c nucleon momentum. Positron spectra from the decay of superdense nuclei are given. Estimations of the probability of superdense nuclei decays are presented

[en] The upper limits of the cross sections for formation of superdense nuclei are determined. They lie between 5x10^-33 and 10^-28 cm² for ₂₈Ni⁵⁸, ₈₂Pb²⁰⁸, ₂₉Cu⁶³, ₇₃Ta¹⁸¹ and ₆C¹² targets irradiated by 1.90, 3.36 or 9.86 GeV/c protons, 0.95 GeV/c per nucleon α-particles and 3.36 GeV/c per nucleon carbon nuclei. Decay particles with energies exceeding 16.4 MeV were searched for

[en] The bubble chamber with a holographic readout is described. Its sizes are: diameter-65 mm, depth-40 mm, filling-freon (C₃H₈) operating temperature-46 deg C, pressure-21 atm. The Gabor scheme of obtaining holograms was used in the setup. The ruby laser with pumping (lambda=694.3 ns), 30 ns length of light pulse, pulse energy of 0.3 Jsub(x) was used for illumination. The chamber was irradiated by the proton beam of a synchrophasotron. QUality holograms of proton-freon interacting are obtained. Density of bubbles in primary proton tracks was 120 cm^-1, that of secondary particles - 1000 cm^-1. Bubble diameter for growth time 10 mks is 10 mkm. The results of photometric measurements of bubble profile and photographs of restored from holograms events of proton-freon interaction are given. Bubbles of >=10 mkm diameter have a good contrast and clear boundaries. Tracks with bubble diameter of >= 5-6 mkm are also registered in holograms

[en] A pulse non-iron magnet is described intended for dosing relativistic nuclei travelling along the channel into 2-metre propane chamber. Leading front of the magnetic field accretion tsub(fr.) = 1 mc. sec. Duration of the field plateau is up to 5 msec. Maximum beam-bending capacity of the magnet Hsub(max) : 1 = 1.7 x 10⁵ epsilon x cm. The magnet has been used at the relativistic nucleus channel continuously for 10 days, and it has ensured the dosage of the pre-determined number of deutons for 2-metre propane chamber with a high selectivity
