Abstract
IN the course of investigations on the electron concentration produced by evaporation of electrons from the carbon particles in the luminous flames of acetylene and air, it was found that the method of microwave attenuation described by Belcher and Sugden1 was not sufficiently sensitive. A more sensitive method of obtaining this concentration is to determine the conductivity of the flame by measuring the change in characteristics of a cavity resonator when the flame is inserted in it.
