Electric discharges in gases — II: Ions in dense gases

This article is a review of some of the established facts and accepted theories pertaining to the behavior of ions in dense gases, supplementing the article that appeared in last month´s issue reviewing current knowledge concerning ionization and excitation, and preparing the way for next month´s article which will discuss various types of electric discharges in the light of the basic processes set forth in this and the preceding article. This is the fourth of a series of special articles developed under the sponsorship of the A.I.E.E. committee on education, and the second of three devoted to the major divisions of the general subject of electric discharges in gases. Full details concerning this series of articles are given on p. 238 of ELECTRICAL ENGINEERING for February 1934.
