Effect of a constant electromagnetic field on the photoproduction of $W^+e^-$ pairs by relativistic neutrinos
V.Ch. Zhukovskii, A.V. Kurilin
The standard Weinberg-Salam-Glashow model is used to calculate the probability of the decay of the neutrino into an electron and the W-boson in a plane-wave field (crossed field + wave). An analysis of a partial expansion of the total decay probability has led to results that describe the photoproduction of $W^+e^-$ pairs by relativistic neutrinos in a crossed field.

An analysis is given of the effect due to the additional neutral vector boson predicted by the 7-dimensional theory of gravielectroweak interactions. The scattering of a muon neutrino by a muon, in which the additional neutral current appears at both high and relatively low energies of the colliding particles, is examined as a special case.

Effect of temperature on the fixing of the main walls in ferrite garnet films
A.G. Shishkov, E.N. Il'icheva, N.B. Shirokova, V.I. Kozlov, Yu.N. Fedyunin, G.A. Bazhazhin
It is shown that the coercive force of a ferrite-garnet film is a temperature-sensitive parameter because of the temperature dependence of the anisotropy field and the energy of the walls. The "period" and "amplitude" of the magnetic potential profile of moving domain walls undergo a change near the compensation point, which is due to the change in the magnetostatic interaction between the domains.

O.G. Koshelev, Т.B. Pleskacheva
A nonintrusive method is proposed for the determination of the surface resistance and mean free time of carriers in a thin layer of a doped semiconductor deposited on a high-resistance substrate whose thickness is insufficient for the observation of the plasma minimum. The method is based on measurement of the infrared transmission of silicon wafers in the wavelength range 20-130 μm.

A determination is reported of the parameters of the Mittag-Leffler expansion that result in the optimum expansion for the reciprocal distance that converges more rapidly tban the universal expansion by the factor $e^{20/l_1^2}$, where $l_1$ is the distance between the nearest mountains and the point of observation. The expansion converges more rapidly at a given point than the Laplace series.

It is shown that this distinguishes the relativistic theory of gravitation from the general theory of relativity "on a flat background."
