Abstract

A method for calculating the electron concentration in dense plasmas containing hydrogen is suggested which utilizes two intensity measurements at separate points within the profile of the H_β line. The relative intensity observed by two detectors is expressed as a function of the electron concentration, plasma temperature, and instrumental parameters such as resolution and wavelength separation between measurements. Electron concentrations between 10¹⁵ cm⁻³ and 10¹⁷ cm⁻³ may be read directly from graphs presented in this article.
