Effect of Change in Pressure and Current Density on the Spectrum of Helium
<p>A study has been made of the intensities of the various lines of the neutral helium spectrum, with the particular view of obtaining regularities in the variation of the relative intensities with changes in current density and pressure.</p> <p>The method used is a modification...
