Abstract

Laser absorption spectroscopy provides high-resolution spectra of atomic transitions that reveal many often inaccessible nuances. Correctly analyzing the absorption spectra is impossible without accurately capturing the line shape. We demonstrate in this work that isotopic effects significantly influence the line shape of krypton transitions in magnetized plasmas. Most interesting is the contribution by the odd-numbered isotope 83Kr due to its hyperfine structure, creating a much more complex spectrum in comparison to even-numbered isotopes. The lines originating from both metastable levels of krypton with J = 2 (760 nm) and J = 0 (785 nm) were measured and analyzed. Evaluating the Hamiltonian, including hyperfine and Zeeman interaction terms, unveils the nonlinear energy shift of the magnetic sublevels and changing relative intensities in the field range of 22.5mT to 90 mT.
