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 Hβ 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.
