Abstract

An alternative approach to the theory of photocounts is discussed. Mechanisms of sharpening of electronic distribution at the expansion of many-electron packets is investigated. Arising of such inhomogeneities initiates a disintegration of many-electron system on smeared on- electron formation. It is shown that interelectronic Coulomb interaction results in the sharpening and localization of such one-electron formations. The motion of an electronic wave packet in the uniform field in the interelectrode space of the vacuum photodetector is investigated. It is shown that the dimensions of such a packet must be of an order or more than one micron. It is shown that such localized charges can give rise to abrupt pulses of the current in the external circuit of the photodetector. The determination of parameters of such a packet by powerful laser pulse scattered is discussed. The motion of one-electron wave packet in the nonuniform field of a negative charged spherical electrode is numerically investigated. It is shown that there is the possibility to unsqueeze electron packets in the transverse direction to macroscopic size by scattering on such electrodes. An experiment of observation of such macroscopic packet on the luminophore screen is discussed.
