Optische Messung der Hyperfeinstrukturaufspaltungen von CoI-Termen

The spectrum of⁵⁹CoI has been investigated by a direct optical method. The hyperfine-splitting of 61 lines between 3,412 and 6,082 Å has been determined. A special numerical technique has been used to decompose the unresolved profiles. For 36 niveaus theA-factors and from these the magnetic field strength at the nucleus have been obtained and also someB-factors. The accuracy of theA-factors lies between 0.5 and 5 percent.
