Abstract
Far UV lines in the spectra of PtII, AuII and BiII emitted by a hollow-cathode lamp exhibit Fabry-Perot patterns, which are used for determining the hyperfine structure of the low-lying levels of these three spectra and the isotopic shifts in five lines of PtII. The experimental data are compared with those computed through the relativistic Dirac-Fock method. The effect of spin polarisation is discussed. In the case ofd electrons the Hartree-Fock method with spin polarisation is used for explaining the large ratio between the spin polarisation and relativistic effects.
