STUDY OF COLLISION PROCESSES IN GASEOUS PLASMAS.

Abstract

The studies were started in 1958 with the measurement of the time dependence of the number density of electrons in decaying plasmas and have been extended by studying the properties of ions, mtastable atoms, etc. This investigation is directed towards (1) the relation between the values of the mobility of positive ions as obtained from time-of-flight studies and those calculated from ambipolar diffusion coefficients measurements. (2) The study of the mechanism of electronpositive ion and negative ion-positive ion recombination, combined with the measurement of the reaction rates involved. (3) The production processes and properties of homonuclear and heteronuclear polyatomic ions. (4) The study of the origin of light omitted by a decaying plasma. (5) The study of the properties of metastable excited atoms. The equipment being used for the studies described has been designed and constructed with the goal of measuring simultaneously the properties of as many plasma constituents as possible.
