Abstract

We analyzed shapes of Hg 253.7 nm spectral line, emitted from a micro–size electrodeless Hg/Xe capillary lamp in a magnetic field for its usage in Zeeman atomic absorption spectrometry. Measurements for several different lamp positions were conducted. Obtained profiles were presented as a Fredholm integral equation of the first kind and separated from an instrumental function. The gas temperature, the dependence of Zeeman splitting on the intensity of the magnetic field, and the magnetic field’s exact value in the experiment were determined.
