Caption: Interferometer readings. This graph shows the results of a test carried out on the isotopes Kr-86 (Krypton 86) and Hg-198 (Mercury 198) by a Fabry-Perot interferometer. Kr-86 has a much narrower line and sharper peak than Hg-198, while the intensity of radiation emitted by Hg-198 becomes higher at lower pressures than Kr-86.
