Proof of a quasi linear equation for a bounded beam
P. Krocek (Czechoslovakia)
A theoretical investigation is made of the problem of quasilinear relaxation of a bounded plane - parallel beam. A derivation is given of a quasilinear transport equation for a bounded beam allowing for specular reflection of electrons by the confining walls; this equation is solved explicitly for a monoenergetic beam. It is shown that at the hydrodynamic stage the quasilinear relaxation of abounded beam is of the same nature as the relaxation of an unbounded beam. A characteristic feature of the relaxation is an inhomogeneity of the electron temperature distribution across the direction of motion.

NMR spectra in the semimedium-coupling range
V.S. Tumanov
General formulas are derived for the semimedium - couplingrange, accurate to the third approximation of perturbation theory for the frequencies and the second approximation for the intensities. A general formula is derived for the fourth-approximation frequencies in the case in which this approximation makes the main contribution to the splitting. It is shown that the spectra of systems of non-equivalent nuclei preserves in the third approximation the structure characteristic for the first - order spectra. General relations are obtained for determination of the sequence of the lines formed as a result of lifting of degeneracy.

Experimental studies of sea-air heat exchange
N.A. Skorokhvatov, E.G. Andreev, and G.G. Khundzhua
The results of field studies of the total heat flux and effective radiation flux of the sea surface that were made during a 1976 Black Sea expedition are reported. Newly developed instruments were used to obtain curves of the diurnal cycles of these fluxes, and comparative data are presented for open-sea and inshore areas. The influence of an oil film on the heat fluxes from the sea into the atmosphere is illustrated.

Induced radiation of an anharmonic oscillator in a strong electromagnetic field
V.F. Korolev
We derive an expression for the power of induced radiation from an anharmonic oscillator in a strong electromagnetic field. It is shown that the maximum radiation power of such an oscillator is obtained in the case that the induced radiation lifetime is much less than the mean time between molecular collisions.

Radiation of a charge in an inhomogeneous magnetic field
V.Ch. Zhukovskii
The radiation of a relativistic charge moving in an inhomogeneous guiding magnetic field of sufficiently smooth form is considered. The polarization-angle characteristic of the radiation are determined as they depend on the vertical deviation of velocity from the equilibrium value. It is shown that there is no explicit dependence of radiation intensity on the radial velocity component in the approximation considered.

Leptonic processes in an ultrastrong magnetic field
V.Ch. Zhukovskii, P.A. Eminov, Sharif Abdullah Hamid (Sudan)
The emission of a massive neutral vector particle by a charged lepton in a magnetic field H and the decay of a resting muon in which an electron is produced in the ground state are considered. The probabilities of these processes are calculated. It is shown that these processes may become most probable in the range of ultrastrong fields $H ≥H_{0}=(m^{2}c^{3})/(e_{0}ħ)= 4,41∙10^{13}$ G.
