PROCESSES OF IONIZATION AND QUENCHING OF EXCITED ATOMS WITH FAST ELECTRONS PRODUCTION

Methods and the results of investigations of the reactions with excite d atoms and examined in the result of which are being formed electrons with the energy exceeding that of a mean energy of the electron distr ibution In a plasma. A special attention is given to the plasma electr onic spectroscopy method (PESM) combining the advantages of studying e lementary processes in a plasma with traditional electronic spectrosco py possibilities. The data concerning a study of chemoionization react ions with two excited atoms of inert gases, penning atoms and molecule s ionization by metastable helium atoms, decaying of excited atoms of inert gases and mercury by electrons are demonstrated. The problem dea ling with the effect of processes with fast electron formation upon pl asma properties is discussed.
