RADIATION CHARACTERISTICS OF METAL VAPORS

Abstract

An experimental program is described in which semi-quantitative data on absorption of radiant energy by alkali metal vapors was obtained. The range of variables covered were: temperature, 250 to 600 C; sodium and potassium vapor pressure, 0 to 18 mm Hg; vapor path length, 4-1/2 and 8-1/2 inches; wavelength region 4000-8300 angstroms. The results are reported in terms of the decrease in intensity of light passing through alkali metal vapors as functions of vapor pressure, tem perature and path length. The absorption of radiation by alkali metal vapors has been shown to have an observable effect on the heat transfer in arc and plasma systems and warrants a more detailed study over a larger spectral range.
