The microstructure of lithium fluoride thin films deposited on a glass substrate by thermal vacuum evaporation was investigated. An additional annealing of the films in air at temperatures of 400, 500, and 600°C resulted in an increase in the size o

The studies of Scotch pine (Pinus sylvestris L.) needles structure and chlorophylls and carotenoid contents were carried out in four districts of the city of Krasnoyarsk, differing in the level of technogenic load. It was shown, that the length of th

Nonlinear stage of the modulational instability of Langmuir oscillations in a beam-plasma experiment
Publikováno v:
Physics Letters A. 110:129-132
Langmuir oscillations with a rather large amplitude, at which a modulational instability is “switched on”, were studied experimentally in a collisionless unmagnetized plasma with an electron beam. In accordance with predictions of a theory advanc
