Technique for measuring the frequency of slow electron collisions with atoms and molecules

The described technique was applied for registering the frequency of slow electrons collisions with molecules and atoms of substances. The registering is carried out through superpositioning of crossing high-frequency electrical and adjustable constant magnetic fields over the investigated media, through inserting in this media electrons with the necessary energy and by registering the forms of the curve that characterizes the electron-cyclotron resonance, by which a judgement can be made about the collision frequency. To lower the electrical field frequency, to simplify the apparatus and widen the nomenclature of the investigated substances a stationary flux of electrons is inserted in the investigated media with the help of thermoionic cathode, for example, hence the resonance curve of the electron power reaching the collector is registered. The described technique can be applied for investigating the plasma parameters. (author)
