Changes in electrical resistance of silver films were measured in the range from 1013 to 103 Ω during thermal deposition on sapphire in a high vacuum, after the deposition over time, and under an applied voltage. The dependences of the electrical re

The changes in the states of excited Rb atoms approaching a singlecrystal sapphire surface have been investigated by methods of laserexcitation spec troscopy and luminescence of Rb vapor in a cell with sapphire windows, the gap between which was vari

Analytical and numerical studies of the energy density spatial distribution of a fluctuating electric field near the model ionic crystal surface as a function of temperature are carried out. It is established that the fluctuating field energy density

In the present work the photoelectric emission from island sodium films was investigated. Appreciable deviations from Fowler's law as well as an increase of the photoelectrons yield for the island films were discovered. The dependences of the photoef

Formation of spatially non-uniform mechanical tension in a transparent solid due to the lattice ionization under the intensive ultrashort laser pulses action is predicted and theoretically described. Within the framework of the continual theory of el

The impact of excited cesium atoms on sapphire and glass surfaces have been experimentally studied. It is established that the probability of electron excitation quenching upon impact of an atom on the dielectric surface is close to unity. The veloci

A new light-induced effect—surface photodiffusion—is found in the processes of transfer on a solid surface. The essence of the effect is that the energy of electronic excitation of an adsorbed atom is transformed into that of its motion over the

Variations in the structural parameters of island sodium films on the quartz surface, caused by heating or exposure to optical radiation, are investigated by the optical method proposed earlier. A correct scheme of processing the measured data is dev

A new optical effect in the transport of atoms in dense gases, capillaries, and porous media is predicted. The origin of this effect lies in superelastic collisions of excited atoms, which give rise to thermal diffusion processes. Model estimates are
