Abstract
FOR the spectroscopic study of the light scattered in solids and fluids using interferometers of high resolving power, it is very important to be able to work with a light source giving sharp and intense spectral lines without accompanying hyperfine structure components or continuous spectrum. A zinc—mercury amalgam lamp in Pyrex glass has been developed in this laboratory by one of us (C. S. V.) Which gives the zinc triplet of lines 4680, 4722 and 4811 A., satisfying these requirements. It may be run continuously for days together without trouble, and is found to be a great advance on the ordinary mercury arcs for such investigations.
