Abstract
A method was developed with which we could easily obtain exact absorption coefficients not only of visible lines but also of ultraviolet lines to determine atom or ion densities in energy levels in a cataphoresis type of positive column gas discharge. This method was applied to a typical He‐metal laser, He‐Cd+ laser, and it has been confirmed that the method gives an accurate value of the Cd+ ion density in the Cd(II) ground level 5s2S1/2.Keywords
