โœฆ Synopsis

The ratio of the absorption coefficients of two Helium lines is measured, and is found in satisfactory accordance with H y 11 e r a a s' theory.

Some years ago Dr. H y 1 1 e r a a s suggested to us to measure the intensity-ratio of heliumlines, in order to check the results of a planned calculation of probabilities of transition. The comparison of theory and observation is simplest when the lines correspond to transitions from a common initi

By means of an interferometer of Fabry and Perot the ,,apparent" intensity distribution in each of the singulet lines of helium 2P--3D, 2.P--4D, 2P--SD and 2S--3P is measured. We suppose that the theoretical intensity distribution in the lines of our helium tube is mainly determined by the D o p p 1
