Spectroscopic study during the extinction of an electric arc
Abstract
The evolution of electron density is measured during extinction of an arc discharge at atmospheric pressure. Measurements are made by spectroscopic methods. Complete local thermodynamic equilibrium is not attained for an electron density lower than 3 by 10 to the 16th power per cu cm. The apparent recombination coefficient for electrons and ions is studied as a function of temperature between 10,000 and 13,000 K.
