ABSTRACT
An alternative approach to the theory ofphotocounts is discussed. Mechanism 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 one-electron formations 1IJ. 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 unifonn 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 then 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 ofparameters of such packet by powerful laser pulse scattered with 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 packet in the transverse direction to macroscopic size by scattering on such electrode. Experiment on observing of such macroscopic packet on the luminophore screen is discussed.
Keywords: electronic emission, vacuum photodetectors, photocounts, shot noise, theory of catastrophes, localization of one-electron formations, squeezed states theory, one-electron wave packets, macroscopic electronic packets.
1. INTRODUCTION
The existing theory of photocounts is largely phenomenological, i.e. it is not a theory that follows from fundamental equations ofphysics (Maxwell, Schrodinger or Dirac equations). For
